Problems of the environmental monitoring of vari-
ous media at a molecular level and tasks arising in the
laboratory practice necessitate the development of
experimental and theoretical methods for the quantita-
tive analysis of chemical substances possessing a rea-
sonable accuracy and predictive ability. The quantita-
tive analysis methods employed for analytical purposes
use, as a rule, various reference samples (standards).
This fact considerably narrows the range of solvable
tasks because of the problem of obtaining standard ref-
erence samples, which is complicated by the huge and
ever-increasing number of known chemical com-
pounds. Moreover, increasingly wider problems of the
recognition and quantitative determination of unknown
substances in mixtures of unknown composition have
been emerging in recent years because of intricate, fre-
quently unknown chemical transformations of toxic
