The S1(1B1) ← S0(1A1) transition in pyrazine has been investigated. High resolution laser induced fluorescence spectra were obtained by crossing a well collimated molecular beam with UV radiation of an intra-cavity frequency doubled ring laser. The extreme resolution enabled us to observe the molecular eigenstates of the electronically excited state. Most of the spectral features of the S1 state could be interpreted in terms of a slightly perturbed axis switched rotor spectrum. The perturbations show up both in the energy levels of the S1 and in the intensities of the observed transitions.

We propose a calibration method for the absolute sensitivity of a spectrometer-detector system by applying laser-induced-fluorescence spectroscopy (LIFS) to a discharge plasma. The object of our experiment is to determine the absolute line intensity emitted from the plasma: For a spectral line, the absolute lower-level population on the tube axis before the laser excitation is determined by the self-absorption method combined with LIFS, which determines its spatial distribution, while the upper-level population is negligible compared with the lower-level population. When intense laser-excitation (broad-line excitation) saturates the upper-level population, its absolute value is given from the lower-level one as determined above. By combining the line intensity and the detector output, we determine the absolute sensitivity of the detection system. The above procedure has been applied to He(I) 504.8-nm and Ne(I) 616.4-nm transitions. The results are compared with our previous determination against a tungsten ribbon lamp.
