| 摘 要： | 我们在XeCl准分子激光多光子电离甲醛分子的研究中,获得了甲醛经过2+1和2+2光子共振激发过程而产生的母体离子和高能离解通道的离子CO+。在电子轰击和单光子电离中占优势的低能阈离解通道离子HCO+,由于态选择性激发的结果而未出现。

| Abstract: | The parent ions (H2CO+) and the descendent ions (CO+) from higher energy dissociation channel, generated by 2+1 and 2+2 photon resonant excited processes respectively, have been found in the multiphoton ionization investigation on formaldehyde with XeCl excimer laser. No HCO+ ions from lower energy dissociation channel (which are dominant in both electron impact and single-photon ionization mass spectra) appear as a result of state-selective excitation. |
