Based on recent high-resolution Hubble Space Telescope Space Telescope Imaging Spectrograph observations over the 1160-1360 Å wavelength region, we have discovered that HD 37903 (the illuminating star of the bright reflection nebula NGC 2023 in Orion) exhibits a rich spectrum of vibrationally excited interstellar H2 absorption. We have identified a total of over 500 H2 lines arising from various rotational levels (as high as J = 13) in all 14 excited vibrational states of the ground electronic…

The results indicate that the H2 fragments identified in the O(1S) + H2(X1Σg+) channel following vacuum ultraviolet (VUV) photodissociation of H2O in the wavelength range of λ = ~100-112 nm are vibrationally excited.

The theory of coupled ionization--dissociation fronts produced when molecular clouds are exposed to radiation from hot stars is discussed, and it is shown that even when a distinct photodissociation region exists, the dissociation front propagates too rapidly for the usual stationary models of PDRs to be applicable.
