N. Manini et S. Oss, A SIMPLE APPROACH TO THE CORRELATION OF ROTOVIBRATIONAL STATES IN 4-ATOMIC MOLECULES, Zeitschrift fur Physik. D, Atoms, molecules and clusters, 32(1-2), 1994, pp. 85-91
The problem of correlation between quantum states of four-atomic molec
ules in different geometrical configurations is reviewed in detail. A
general, still simple rule is obtained which allows one to correlate s
tates of a linear four-atomic molecule with those of any kind of non-l
inear four-atomic molecule.
