Abstract

A series of experiments was conducted in which trimethylbismuthine (TMB) was used to introduce atomic bismuth into a supersonic flow of electronically excited nitrogen fluoride, NF(a¹Δ), at an elevated density of 3 x 10¹⁵ mol cm^-3. Excited-state densities of Bi(²D) approximately equal to 1 x 10¹³ atom cm^-3 and BiF(AO⁺) approximately equal to 4 x 1O¹¹ mol cm^-3 were achieved. After correction for mixing, these density values agreed reasonably well with values predicted by a quadratic scaling law. Simulation of the blue BiF(AO⁺)-BiF(XO⁺) emission spectrum suggests that the BiF(AO⁺) was in vibrational as well as rotational equilibrium at 300°C. The significance of these results for developing a supersonic BiF(AO⁺) laser utilizing TMB is discussed.
