Ni. Butkovskaya et al., INFRARED CHEMILUMINESCENCE FROM THE NO- OBSERVATION OF THE 2-NU(1)-NU(1) HOT-BAND OF HNO(HCO REACTION ), Chemical physics letters, 266(1-2), 1997, pp. 223-226
Infrared chemiluminescence in the 2200-3000 cm(-1) range was observed
from vibrationally excited HNO molecules produced in the reaction of N
O with HCO. Formyl radicals were obtained from the OH + CH2O reaction
in a fast-flow reactor connected with a Fourier transform spectrometer
. The HNO spectrum consists of Delta nu(1) = -1 transitions from the (
1 nu(2) nu(3)) and (200) levels. The anharmonicity coefficient x(11) =
-116+/-1 cm(-1) was obtained from the position of the center of the (
002)-(001) hot band, nu(0) = 2452 cm(-1).
