The IR spectra of anthracene-h(10) and -d(10) have been recorded for the first time in the gas phase from 450 to 3200 cm(-1) with a resolution of 0.2 cm(-1), using a multipass cell heated to 100 degrees C. For the assignment of vibrational bands we have evaluated the theoretical spectrum using density functional theory (DFT) and scaled self consistent held force fields. We found that both methods reproduce the sequence of the experimental frequencies to a good accuracy, allowing in most cases consistent and unambiguous assignments. The relative intensities of C14H10 and C14D10 have also been measured and compared to theory.
