In highly excited states however, they shift towards the far infrared and millimeter wave domain. Let us consider the very simple hydrogen energy spectrum formula: E = − R/n2 where E is the level energy measured from the ionization, R the Rydberg constant and n the principal quantum number. The distance between successive levels DE ∼ n-3 which is in the visible and infrared domain for small n becomes in the millimeter range for n ∼ 30.","PeriodicalId":254777,"journal":{"name":"1981 International Conference on Submillimeter Waves and Their Applications","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122633563","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}

Remote sensing working in the wavelength regions from λ = 3 μm to λ = 5 μm and from λ = 8 μm to λ = 14 μm, with high atmospheric transparency is hampered by absorption and thermal emission of the intervening atmosphere. Furthermore, both the global energy balance and the radiative heating loss of the outdoor surface of building envelopes crucially depend on atmospheric thermal emission |1|.","PeriodicalId":254777,"journal":{"name":"1981 International Conference on Submillimeter Waves and Their Applications","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128287146","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 is readily _, apparent in the region less than 100 cm where calculations using standard line-shapes differ from experimental data by factors of 2, 3 or larger. Explanations for this include incorrect lineshape functions, the presence of dimers or water clusters, or a combined effect due to several causes. Our purpose in doing this experiment has been to generate a large data base including absorption coefficients at several frequencies and for many different combinations of water vapor and total pressure. Hopefully, this data will provide sufficient information in order to generate a more accurate water vapor absorption model and understand the cause of the difference in the experimental and theoretical values.","PeriodicalId":254777,"journal":{"name":"1981 International Conference on Submillimeter Waves and Their Applications","volume":"316 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124477371","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 spectra were obtained using 9 bandpass transmission filters in the wavelength range between 12 and 300 microns. Data on the construction, thickness, and rms surface roughness of the coatings are also presented. The chemical composition of two coatings can be distinguished from that of the others by a strong absorption feature between 20 and 40 microns which is attributed to amorphous silicate material. Inverse relationships between these spectra and coating roughness and thickness are noted and lead to development of a single reflecting-layer model for the measured reflectance. The model is applied to the spectra of several coatings whose construction falls within its constraints.","PeriodicalId":254777,"journal":{"name":"1981 International Conference on Submillimeter Waves and Their Applications","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126811257","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}
