Experimental Values

The fluorescence spectra of three coumarin derivatives are studied. Geometric configurations of the three compounds are optimized by DFT method of quantum chemistry on B3LYP/6-31G. There is no imaginary frequency in vibrational analysis. Their excitation spectra are calculated by TD-DFT method. Furthermore, geometric configurations in excited state of the three compounds are optimized by CIS method. Based on the excited configuration emission spectra are also calculated. All the calculated results are in good agreement with experimental values.

Excitation Spectra

A rotation–vibration analysis of the CaFB2S+–X2Σ+ system is reported. Excitation spectra of CaF are recorded with a cw, 1 MHz bandwidth, dye laser combined with restricted-bandpass (2 Å) fluorescence detection. The accuracy of line measurements is 0.003 cm−1. Nine bands in the Δν = 0 sequence are analyzed (ν″ = 0–2,8,9, 12–15) and selected lines in four Δν = −1 bands (ν″ = 1–4) are used to obtain band origins needed for the vibrational analysis. The main constants (1σ error in parentheses) for the CaF B2Σ+ state are: Te = 18 841.309(3) cm−1. Be = 0.342604(7) cm−1, ωe = 572.405(36) cm−1, αe = 0.002630(6) cm−1, ωexe = 3.143(13) cm−1, Re = 1.955 Å. The B2Σ+ state is found to be in pure precession with A2Π with l = 1.
