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 kinetic

We have studied the infrared spectra of the OH(D) hydrogen bonds from the water and NH(D) bonds from the NH2 group in the title compound as functions of deuterium concentration and temperature. Som...

A polycrystalline sample of the title compound containing a small fraction of deuterium was irradiated in an infrared region containing no apparent absorption bands. Holes and antiholes were produced in the N−D stretching bands. Each irradiation th

Monodeuterated derivatives of the salts of tyrosine, valine, glycylglycine, and glycylglycylglycine are investigated by infrared spectroscopy. Irradiation in the spectral region of the N -D stretch bands produces spectral holes and antiholes. These r

The title compound doped with a small amount of deuterium shows infrared bands due to the N−D and O−D stretching vibrations. When one of the N−D bands is irradiated with an infrared laser, holes and anti-holes are produced. The pattern of these
