分子光谱传统上是在频域中解释的,最近在时域中解释。对于简单的吸收和发射光谱,它们是彼此的傅里叶变换。在本文中,我们说明,它可以是有用的,以检查频谱在一个折衷的表示,平衡时间和能量的不确定性。在本文中,我们给出的基本思想和几个例子,揭示隐藏在能量或时间表示的动力学效应。由此产生的“振动图”可从实验光谱或理论计算中获得。
Molecular spectra have traditionally been interpreted in the frequency domain and more recently in the time domain. For simple absorption and emission spectra these are the Fourier transform of one another. In this paper we illustrate that it can be useful to examine spectra in a compromise representation which balances uncertainties in time and energy. In this paper we give the basic ideas and several examples which reveal dynamical effects hidden in either energy or time representations. The resulting ‘‘vibrogram’’ is available from experimental spectra or theoretical calculations.
