| 摘 要： | Ionization and dissociation of nitrosyl chloride ClNO were studied using femtosecond laser mass spectra tech-nique.Strong fragmental ions NO~ and Cl~ were observed with the laser intensity varied from 3.2×10~(14) to 2.5×10~(15) W/cm~2.These fragmental ions were attributed to the direct dissociation of the parent ions.Electronic structurecalculations were also carried out with Hartree-Fock,density functional and correlated levels of theory to under-stand the possible fragmentation pathways.The very low N-Cl bond energy in the parent ion of nitrosyl chloride isa clear reason for the absence of ClNO~ and ClN~ ion peaks from the femtosecond laser mass spectrum.

| Abstract: | Ionization and dissociation of nitrosyl chloride ClNO were studied using femtosecond laser mass spectra technique. Strong fragmental ions NO+and Cl+were observed with the laser intensity varied from 3.2×1014 to 2.5×1015 W/cm2. These fragmental ions were attributed to the direct dissociation of the parent ions. Electronic structure calculations were also carried out with Hartree‐Fock, density functional and correlated levels of theory to understand the possible fragmentation pathways. The very low N–Cl bond energy in the parent ion of nitrosyl chloride is a clear reason for the absence of ClNO+ and ClN+ ion peaks from the femtosecond laser mass spectrum. |
