Abstract

Estimates of the band intensities of transitions between the ground and upper vibrational levels (1-9) were made for HI. Calculations were performed with both Morse and RKR oscillator wavefunctions, using various functional approximations for the dipole operator fitted to known experimental results. Absorption measurements using a multiple pass cell placed upper bounds on transition intensities, which were not inconsistent with the calculated values. (Band strengths for HI ΔV = 8,9 are less than 5 x 10(-4) cm^(-2) atm(^1)). The feasibility of using these multiquantum vibrational transitions to pump the reaction HI + HI*(v - 8,9) → H_2 + 2I is discussed.
