dc.description.abstract | 吾人利用共振腔振盪衰減光譜法觀測C6H5O在1150-1330nm光區之吸收光譜。其中,C6H5O係由193nm雷射光光解氣態之甲氧苯(C6H5OCH3)和乙氧苯(C6H5OC2H5)產生。在8097cm^-1、8360cm^-1、8403cm^-1和8630cm^-1觀測到C6H5O之躍遷的電振吸收譜帶。由理論計算所得之電子態能階及激發態振動波數之結果和譜帶輪廓的指認,上述譜帶可分別指派為12、14、17和18躍遷,而8148cm^-1、8197cm^-1和8451cm^-1可分別指派為 1420、1420、1720熱譜帶,其中(186cm^-1)是C6H5O之基態的最低能量之振動模。在8540cm^-1和8607cm^-1亦觀測到微弱之吸收譜帶,根據計算之結果,暫時指派為15、16躍遷。此外吾人亦觀察到在7681cm^-1之吸收譜帶為躍遷譜帶起始點,與利用UB3LYP/6-311++G(3df,3pd)和CASPT2(9,8)/cc-pVDZ之計算方法所得之能量分別為7304cm^-1和8032cm^-1,僅相差約5%。 | zh_TW |
