Аннотация:Based on a comparison of the measured values of the absorption coefficient at a frequency of v = 357.516 cm-1 In water vapor and those calculated using the phenomenological theory, recom¬mendations are set forth for selecting the Einstein coeffici¬ent and the collisional half-height width of the spectral line for the transition 020(550)—> 001(633) of the H20 molecule.
