A spectroscopic investigation of O2 isolated in D2 matrices is reported. Standard matrix isolation
methods lead to only a small observable concentration of isolated molecules in D2 and fail in the
case of H2. Both resonant excitation of the molecule over the A (3
u)X(3
g ) transition, and
dissociative pumping at 193 nm, lead to vibrationally relaxed A X emission, with a lifetime of
5.4 s. Independent of the initial component accessed, the fluorescence is polarized with a
polarization ratio of 1.25 0.05; indicating that O2 does not rotate and that the transition gains its
intensity by crystal field induced mixing between the 3
u and a nearby 3
