Abstract

The K-subband structure of the acetylenic CH stretch fundamental, nu1, of propargyl radical, CH2CCH, has been assigned and analyzed. The K = 0, 1-, 1+, 3, 4, 5, and 6 upper state energies totaling 109 levels could be accurately fitted with Watson's fourth-order A-reduced Hamiltonian. The K = 2 subband was perturbed with the level crossing between N = 17 and 18. Copyright 1998 Academic Press. Copyright 1998Academic Press
