Abstract
New local modes due to substitutional carbon, C-As, have been detected at 5 66.2 cm(-1) and at 1134.2 and 1149.3 cm(-1) respectively, by Fourier transf orm infrared absorption spectroscopy. The bands are attributed to excited-s tate transitions of the carbon local oscillator. Based on a comparison with recent theoretical predictions, the energy-level diagram including anharmo nicity is discussed. (C) 1999 Elsevier Science B.V. All rights reserved.
