The N-D stretching region in the infrared spectrum of the ammonia complex of tris-(2-methoxymethyl-phenol)-borane containing one D atom has been examined. The N-D bands have been hole burned, and the resulting spectra reveal the reorientation kinetics of the ammonia. The ammonia is hydrogen bonded with the bond distances and reorientation barrier typical of other compounds. The N-D stretching frequencies are higher than those of comparison compounds.

The borane-ammonia complex shows hydrogen bonding and high N-D stretching frequencies, revealing reorientation kinetics and hydrogen bonding typical of other compounds.
