✦ Synopsis

The rotational spectra of NiF in the electronic ground 2 state and the lowest electronically excited 2 state have been observed. The source of nickel atom was sputtering from a nickel electrode or nickel powder placed on a stainless steel electrode. The molecular constants have been determined by a least-squares analysis of the observed transition frequencies. The rapid increase in the -type splittings in the ground state reveals that the observed rotational transitions are ascribed to the spin substate 2 3/2 . The rotational transitions corresponding to the other substate, 2 1/2 , have not been observed. The large spin-rotation interaction constant γ in the electronically excited 2 state is consistent with that from the electronic spectroscopy.

The resonance Raman spectra of the lowest lying singlet (S 1 ) state of free-base tetraphenylporphyrin and seven of its isotopomers were recorded under pump-and-probe conditions with a time delay of -2 ns between pump and probe laser pulses. In the S 1 spectra of the isotopomers, as in the ground st
