✦ Synopsis

The emission spectrum of the 0-0 band of the C 2 S / -X 2 P transition for 12 CH and 13 CH isotopic molecules have been obtained using a Geissler tube. The spectra have been photographed under high resolution and calibrated against Th standard lines. The reduction of the spectra for the individual bands has been performed via a nonlinear least-squares fit with the effective Hamiltonian of Brown. New values of the molecular constants for upper state have been determined. The 0-0 band of the C 2 S / -X 2 P system in the 13 CH radical has been obtained and analyzed for the first time. ᭧ 1997

In the 13 CH / isotopic ion radical emission spectra of six bands of the A 1 P-X 1 S / system have been obtained using a Geissler-type discharge tube. The spectra have been photographed at high resolution and Th standard lines have been used as a calibration spectrum. The 1-1 band has been observed
