采用激光解吸电离飞行时间质谱 (LDI TOF MS)快速测定了 1H 2 ,3 二氢 1 吡咯里嗪酮衍生物相对分子质量 ,初步总结了该类化合物的质谱规律 .实验中不需加入基质 ,实测值与理论计算值相吻合 .
The relative molecular mass of 1, 2, 3-dihydro-1-pyrrolizinone derivatives was determined by laser desorption / ionization time of flight mass spectrometry (LDI TOF MS), and the mass spectra of these compounds were summarized. The values match the theoretical calculations.
