【摘要】 实验研究了间乙氧基苯酚的共振增强多光子电离光谱、烧孔光谱和质量分辨阈值电离光谱。确定了在超声分子束中间乙氧基苯酚只存在一个稳定的分子构型。报道分子的激发态和离子基态光谱,结合密度泛函理论计算分析和指认了观察到的激发态和离子基态的振动频率,确定了基态到第一电子激发态的S₁←S₀跃迁的激发能和精确的绝热电离能分别为（35 892±2）和（63 317±5） cm^-1。更多还原

【Abstract】 The resonance enhanced multiphoton ionization,hole burning,and mass resolution threshold ionization spectra of methoxyphenol were experimentally studied.We experimently confirmed that there is only one stable molecular configuration in the ultrasonic molecular beam.This is the first report on the molecular excited state and ion ground state spectra.Combining with density functional theory calculation we analyzed and identified the vibratiom frequencies observed in the excited state and ionic ground state,and determined the excitation energy of the S₁←S₀ transition and the precise adiabatic ionization energy of m-ethoxyphenol are（35 892± 2） and（63 317±5） cm^-1,respectively.更多还原
