五十年代以来,由于分析仪器的不断发展和应用,现代波谱技术已经逐步代替化学分析,有样品用量少、分析速度快、鉴定结果准确等优点。常用的有光谱、质谱和共振谱,各有其特色,可以取长补短,或联用,或不联用,随着分子结构的复杂或简单而定。下面仅从鉴定的角度,对这些谱的功能简单说明。 Since the 1950s, due to the continuous development and application of analytical instruments, modern spectroscopic techniques have gradually replaced chemical analysis with the advantages of less sample consumption, faster analysis, and accurate identification results. Common spectrum, mass spectrum and resonance spectrum, each with its own characteristics, can learn from each other, or with, or not with the molecular structure of the complex or simple. Below only from the identification point of view, the function of these simple description of the spectrum.
