FOURIER-TRANSFORM EMISSION-SPECTROSCOPY OF THE A'(3)PHI-X(3)PHI SYSTEM OF COH

The emission spectrum of CoH has been investigated in the red and infr ared regions using a Fourier transform spectrometer. The bands observe d in the 1 mu m-800 nm spectral region have been classified into (3) P hi(3)-(3) Phi(3) and (3) Phi(4)-(3) Phi(4) subbands of a new electroni c transition A'(3) Phi-X(3) Phi. The rational analysis of the 0-1 and 0-0 bands of the (3) Phi(4)-(3) Phi(4) subband and the 0-0 band of the (3) Phi(3)-(3) Phi(3) subband has been obtained and the spectroscopic constants have been determined. The effective principal equilibrium c onstants for the lowest energy spin component, X(3) Phi(4), obtained f rom this work are Delta G(1/2) = 1858.7932(32) cm(-1), B-e = 7.255382( 74) cm(-1), alpha(e) = 0.212444(93) cm(-1), and r(e) = 1.531291(8) Ang strom.
