Coriolis analysis of several high-resolution infrared bands of bicyclo[1Â 1Â 1]pentane-d0 and -d1

► High resolution infrared spectra of spiropentane (C5H8) and a deuterated form (C5H7D). ► An analysis that accounts for spectral complications caused by Coriolis interactions. ► Rovibrational parameters for ground and excited vibrational states. ► Comparisons with theoretical results from quantum calculations at the anharmonic level.
