The addition of a small percent of nitrogen to GaAs causes a large reduction of the band gap energy and a tensile strain within the lattice. The further addition of H at 300 \ifmmode^\circ\else\textdegree\fi{}C causes a recovery of the band gap of th

The H-N-H center in ${\text{GaAs}}_{1\ensuremath{-}y}{\text{N}}_{y}$ that is responsible for the band-gap shift caused by H has been studied by infrared spectroscopy in conjunction with uniaxial stress and by theory. Rich, microscopic details about i

Measurements of the O-H and O-D vibrational lifetimes show that the room-temperature hydrogen diffusion rate in rutile TiO2 can be enhanced by 9 orders of magnitude when stimulated by resonant infrared light. We find that the local oscillatory motion

Hydrogen is commonly introduced into silicon solar cells to reduce the deleterious effects of defects and to increase cell efficiency. We have developed strategies by which hydrogen in silicon can be detected by IR spectroscopy with high sensitivity.

The vibrational lifetimes of the O-H and O-D stretch modes in the perovskite oxide KTaO 3 are measured by pump-probe infrared spectroscopy. Both stretch modes are exceptionally long lived and exhibit a large "reverse" isotope effect, due to a phonon-
