英文摘要：
The photoionization and dissociative photoionization of 1-propanol and 2-propanols have been studied at the photon energy range of 9.84～11.80 eV. Photoionization efficiency spectra for ions CH3CH6SHOH^＋、CH2CH20H^＋、CH3CH2CH2^＋、CH3CH=CH2^＋ from 1-propanol, and CH3CH（OH）CH3^＋、CH3C（OH）CH3^＋、CH3CHOH^＋、CH2=CHOH^＋、CH3CHCH3^＋ from 2-propanol have been measured. In addition, the energetics of the dissociative photoionization has been examined by ab initio Gaussion-3（G3） calculations. The computational results are useful in establishing the dissociation channels near the ionization thresholds. With the help of G3 results, the dissociation channels for formation of the fragment ions CH3CH2CHOH^＋、CH2CH2OH^＋、CH3CH2CH2^＋、CH3CH=CH2^＋、CH2OH^＋ from 1-propanol, and CH3C（OH）CH3^＋、CH3CHOH^＋、CH2=CHOH^＋,CH3CHCH3^＋、CH3CH=CH2^＋ from 2- propanol have been established. The G3 results are in excellent agreement with the experimental data.
