摘要

The problem of concentration measurements of harmful gases existing in the boundary layer of atmosphere is very important for ecological monitoring. Depending on the molecular structure of par- ticular gas, its absorption bands have a clear fine structure. Such gases as NO_2, SO_2, and the like have fine structure of absorption oscillating bands in the form of equidistant bands. Oscillating bands of aromatic hydrocarbons have a complex structure in ultraviolet spectrum range (240-280) nm in which they can be easily identified, while in infrared range these bands are in fact covered and there is no possibility to separate them distinctly.
