Abstract:

The infrared spectra of ammonia-borane, BH3NH3, and two of its deuterated isotopic species, BD3ND3 and BH3ND3, isolated in argon matrix at liquid hydrogen temperature have been measured. Well resolved bands, for these three isotopic species, have been observed for all the fundamentals. A complete frequency assignment has been made based on a molecular symmetry of C3v. Using a valence force field, a set of force constants have been calculated from the data for the two isotopes BH3NH3, and BD3ND3. The agreement between experiment and calculated frequencies from these force constants for the mixed isotopic species, BH3ND3, substantiates the present assignment. Author
