ENERGY LEVELS OF POLYATOMIC MOLECULES. PART ONE.
Abstract
The rotation-vibration energies of polyatomic molecules were computed to the fourth order of approximation. These energies are used to obtain the frequencies of lines in rotation and rotation-vibration spectra. Such very accurate calculations are necessary in order to explain many effects observed in very high resolution spectra. The following topics are emphasized: the quartic anharmonic potential function; the rotation spectrum of axially symmetric molecules in an excited vibrational state; the rotation-vibration spectra of spherical top molecules; anomalous rotational structure of level 03(1)1 in the rotation-vibration spectrum of C(13) O2(16); rotational structure of the fundamental NU6 of methyl cyanide; a general discussion of Fermi resonance in CO2 with a new assignment of vibrational levels.
