ABSTRACT
The spectra presented in this Handbook were obtained for either of two objectives. The first major objective was possible detection and measurement of new constituents in the earth’s atmosphere. In most cases, the expected atmospheric absorptions from such a constituent will be quite weak. Therefore, the amount of gas in the absorption cell was adjusted so that the peak absorption in the spectrum was less than 50%. However, in some cases portions of the band may be strong enough that this criterion was exceeded.
