Abstract
We calculate the harmonic spectrum generated by a model HD molecule in a st rong laser pulse. The unequal nuclear masses lead to the emission of even h armonics, i.e., photon frequencies which are even multiples of the laser fr equency. The effect does not occur within the Born-Oppenheimer approximatio n. In the high-frequency region, the even harmonics are almost of the same order of magnitude as the odd ones.
