Notes:
The dispersed fluorescence (DF) spectra for the fluorescence emitted from eight single rovibronic levels in the C˜ 1B2 state are observed. The vibrational quantum numbers for these levels are (v'1,v2,v'3) =(0,0,0), (0,1,0), (0,2,0), (0,0,2), (1,0,0), (1,1,0), (1,2,2), and (3,1,0). The 484 vibrational levels distributed between 4300 and 21 600 cm−1 in the electronic ground state X˜ 1A1 are identified based on the assignment of the 1388 transitions in the DF spectra. The vibrational level energy is expressed by an anharmonic expansion with 19 coefficients and the vibrational quanta for the three normal modes. The combination analysis of the DF and stimulated emission pumping spectra having the same upper rovibronic level clarifies the vibrational level structure in the vibrationally highly excited region above 17 000 cm−1.
