The collisional enhancing of the magnetic dipole transition I(52P1/2–52P3/2) at 1.3152 μm by Xe is shown to proceed over an exciplex channel: I(52P1/2) + Xe → XeI(2π1/2) → I(52P3/2) + Xe + hν(1.3 μm). The pseudo-first-order rate coefficient for this process is (1.6 ± 0.2) × 10−18 molecule−1 cm3 sec−1. The termolecular rate coefficient for XeI(2π1/2) excimer production is (2 ± 1) × 10−35 molecule−2 cm6 sec−1. The radiative lifetime of the XeI excimer state is of the order of 100 nsec. Similar effects are briefly reported for C2F6, SF6 Kr, Ar, and i-C3F7I.
