The (A)over-tilde <-(X)over-tilde (1+1) resonance-enhanced multiphoton ionization spectrum of the NO center dot C2H6 and NO center dot(C2H6)(2) complexes
The (A) over tilde <-- <(X)over tilde> transitions of NO .C2H6 and NO bullet>(*) over bar * (C2H6)(2) have been recorded using (1 + 1) resonance-enhanced multiphoton ionization spectroscopy. The NO .C2H6 origin is determined to be 44050 +/- 15 cm(-1), and the dissociation energy, D-0', of the (A) over tilde state is measured to be 340 +/- 20 cm(-1). The latter values allow the dissociation energy of the (X) over tilde state, D-0", to be determined as 190 +/- 20 cm(-1). In addition, estimates of the dissociation energies for the processes NO bullet>(*) over bar * (C2H6)(2) + NO .C2H6 + C2H6 and NO bullet>(*) over bar * (C2H6)(2) --> NO + 2C(2)H(6) in the (X) over tilde and (A) over tilde states are obtained; the (A) over tilde state is found to be dissociative along the NO .C2H6. . .C2H6 coordinate. Comparison of the NO .C2H6 (A) over tilde <-- <(X)over tilde> spectrum with that of NO . CH4 is made.
