摘要: Experiments in molecular spectroscopy involve the three main steps of sample preparation, scanning or dispersing photon frequencies over range to be studied and signal detection. There then follows assignments spectral lines measurement dynamics quantum states. Unfortunately, classical linear with spectrometers optimisation one part experiment often degrades performance another part. For example, emission high resolution conflicts sensitivity fast time resolution. Furthermore, many spectra have such a congested line density complex structure that they may defy all attempts at unambiguous assignment.
