Abstract
CAS(12,11)/cc-pVDZ and CAS(12,11)/aug-cc-pVTZ calculations have been employed to investigate the reaction of CH + NO → products on the singlet energy surface and the possible reaction channels have been explored. Three intermediates, such as cis-HCON, trans-HCON and linear HCNO, are formed when methylidyne radical CH(X2Π) collides with nitrogen monoxide NO(2Π). After a series of the rearrangement and fission, the final stable products yield. In order to get more accurate energetics, single-point CAS(10,10) + 1 + 2//CAS(12,11)/cc-pVDZ calculations have been performed for comparison.
