Popis: High-resolution (≤2.4×10−3cm−1) Fourier transform infrared spectra of gas-phase 10B-enriched isotopic and natural samples of BF2OH (difluoroboric acid) were recorded in the 400–4000 cm−1 spectral range. Starting from the results of a previous study [Collet, D., Perrin, A., Burger, H., and Flaud, J.-M., 2002, J. Molec. Spectrosc. 212, 118], which involved the v 8 10BF2 out-of-plane bending) and v9 (OH torsion) bands of 11BF2OH, it has been possible to perform the first rovibrational analysis of the v 5 10BF2 bending), v 8 , v 9 and v 8+v 9 bands of’11BF2OH, and of the v 7 (F2BO in-plane bending), v 5, and v 8+v9 bands of 11BF2OH up to very high rotational quantum numbers. In addition, microwave transitions within the 51, 61, 71 and 81 vibrational states of 11BF2OH were measured using predictions from ab initio calculations [Breidung, J., Demaison, J., D'Eu, J.-F., Margules, L., Collet, D., Mkadmi, E. B., Perrtn, A., And Thiel, W., 2004, J. Mol. S ectrosc. (in press)]. The v 5, v 8, v 9 and v 8+v 9...
