Laser excitation spectra of the system of CaNH2 are reported. Due to the spectral density, individual lines could only be resolved and measured using a filtered fluorescence excitation technique, with a monochromator acting as an optical bandpass filter; 140 line positions were measured in this way and assigned to the parallel K?1 = 1 subband of what is believed to be the vibrational 0-0 band. The molecular constants were determined from a weighted nonlinear least-squares fit of the line positions.
