In amorphous media the local environments for impurity centers are continuously changing with time. As a result transition frequencies of individual centers diffuse within the inhomogeneous broadened spectral contour, which is called spectral diffusion. When the timescale for spectral diffusion processes is much longer than the dephasing time, it is possible to distinguish homogeneous dephasing from spectral diffusion. On the other hand, when the timescales of spectral diffusion and dephasing processes are comparable these phenomena become indistinguishable.","PeriodicalId":443330,"journal":{"name":"Spectral Hole-Burning and Related Spectroscopies: Science and Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130806766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Spectroscopic techniques based on the appearence of optical zero phonon lines, such as fluorescence line narrowing, spectral hole-burning, and single molecule spectroscopy provide an experimental resolution limited by the homogeneous linewidth. From the investigation of the homogeneous line width as a function of different parameters (time, temperature) information on the guest host interactions responsible for the observed linewidth is obtained. Spectrally narrow features are extremely sensitive probes for external perturbations, such as electric fields, magnetic fields, or hydrostatic pressure.","PeriodicalId":443330,"journal":{"name":"Spectral Hole-Burning and Related Spectroscopies: Science and Applications","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130947856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This characteristics of the porphyrin-PVA system is due to the facts that the Debye-Waller factor is relatively large [3] and the thermally activated backward reaction is small [4], Figure 1(a) shows one of such porphyrin molecules, TCPP(Na). The large Debye-Waller factor in porphyrin-PVA system is a direct consequence of a high mean phonon frequency. The typical phonon energy of the porphyrin-PVA system, which was determined as the energy deference between the zero-phonon hole and the bottom of the side hole, is as large as 25 cm–1. According to ref. 3, the Debye-Waller factor f(T) of porphyrin-PVA system is well represented by one-phonon approximation.","PeriodicalId":443330,"journal":{"name":"Spectral Hole-Burning and Related Spectroscopies: Science and Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129714080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dab","doi":"10.1364/shbs.1994.the1","DOIUrl":"https://doi.org/10.1364/shbs.1994.the1","url":null,"abstract":"A theoretical method that systematically finds tunneling systems in glasses and allows a microscopic justification of the standard tunneling model of Phillips and Anderson, Halperin and Varma is presented. The calculation shows that the major assumptions of the tunneling model are qualitatively correct; however, there are small deviations in the distribution functions of tunneling parameters that give rise to the T1+ε law for specific heat and the T2-α law for the thermal conductivity. The calculation also allows a quantitative estimate of the interaction of the two level systems with phonons (the deformation potential). The calculations confirm the weak coupling picture, in contrast with recent conjectures. The theory is then mapped onto all structural glasses via a Lennard-Jones model for the interaction between sub-units in the glass. These sub-units are molecular systems (e.g monomers in a polymer glass or tetrahedra in silicate glasses). From this mapping, we find that the tunneling parameters, and hence the thermal properties, of most structural glasses can be estimated semi-quantitatively from the microscopic parameters of the Hamiltonian. A further argument allows the connection between the tunneling parameters and the macroscopic experimental properties (sound velocity and density) to be drawn. The calculations also go smoothly into the \"soft potential\" model that explains the thermal behavior at higher temperatures (~10K), thus providing a universal model. From these calculations, the distribution of tunneling rates that give rise to spectral diffusion can be calculated and compared to recent experiments. These will be presented at the conference, along with calculations of the effect on the two level system distributions of introducing an impurity (i.e. chromophore) into the glass.","PeriodicalId":443330,"journal":{"name":"Spectral Hole-Burning and Related Spectroscopies: Science and Applications","volume":"154 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121534189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The PSHB in fluorescence has been measured in antenna complexes: CP43 and CP47 of PSII [3], B800-850 of purple photosynthetic bacteria [4] and in chlorosomes of green sulphur photosynthetic bacteria [5]. Laser induced hole filling in fluorescence spectra of CP43 of PSII was presented recently in [6]. These data were obtained using wild type organisms.
