The original spectrum can be recovered by solving two types of integral equations successively. The theory of Hilbert and Schmidt is applied to those solutions. The resolution attained with this method approaches to the theoretical one. The recovered spectrum well corresponds to the original one even in the presence of noise of the order of 10-2. It was verified that when the number of calculating points is small (-100), the recovery can be done by a personal computer in the laboratory. Some results by a computer simulation show that this mathematically rigorous method is useful in practice.","PeriodicalId":199016,"journal":{"name":"Journal of the Spectroscopical Society of Japan","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129772219","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 method consists of the measurement of an emission spectrum of a gaseous sample, and measurement of the amount of its attenuation caused by placing an absorption gas cell filled with the same chemical species as that emitted. If the line width of either emitting or absorption gas is known, the line width of the other can be obtained by calculation. Two sets of experiments were conducted on carbon monoxide (CO); (1) measurement of pressure broadening in the line widths of the absorption lines of CO by the use of narrow CO emission lines, (2) measurement of the line widths in the emission lines of CO by the use of a set of absorption lines of CO, whose widths are known. As a result, the translational temperature of the emission system was determined.","PeriodicalId":199016,"journal":{"name":"Journal of the Spectroscopical Society of Japan","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133073985","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 experimental values for polystyrene microparticles, radii 0.4-5.2 μm, agreed with the theoretical values within the experimental accuracy of ±0.2 deg. The physical meaning of the phase shift was clarified as representing the delay angle of the photoacoustic signal generation determined by the ratio of the heat release time from the microparticles to the modulation period of the excitation beam.Applications of photoacoustic spectroscopy for sizing and determination of microparticles in liquids by proper use of modulation frequency are discussed.","PeriodicalId":199016,"journal":{"name":"Journal of the Spectroscopical Society of Japan","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131533961","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 photon pulses of luminescence decays are temporarily stored in 64-bit shift registers with a time resolution of 5 or 10 ns and accumulated. The decay curves are efficiently measured in time sharing over the time range from 0 to 81.2 μs when the resolution of 5 ns is selected. The maximum repetition times and the maximum repetition rates are 65536 times and 20 starts/s, respectively. The instrument is aided by a personal computer and much available for measurements of luminescence decays having a decay time of around 100 ns. Also, a wide variety of applications should be found in luminescence spectroscopy. The performance has been shown by measurements of light pulses from a light emitting diode.","PeriodicalId":199016,"journal":{"name":"Journal of the Spectroscopical Society of Japan","volume":"57 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133142398","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 sine-bar and its driving system are disabled and the grating is driven directly by a synchronous motor.

In an on-line and real-time mode, a variety of measurements can be achieved by a dedicated microcomputer.

On the other hand, the excitation functions of the radial coupling increase rapidly near threshold energy and take their maximum values at low colliding energy compared with those of rotational coupling.
