The electron impact induced fragmentations of the title compound, its methyl ester, its three hydroxy derivatives, namely, 3-hydroxy alpha- and beta-hydroxy, their acetyl methyl esters and its 2,3-dehydro derivative, have been studied in detail. Among the uncommon features of the observed processes were methyl acetate and C-2 and C-3 hydrocarbon expulsions and a few novel rearrangements. The ion at m/z 131 appeared as the terminal for many fragmentation sequences.
已详细研究了标题化合物、其甲酯、其三种羟基衍生物（即3-羟基、α-羟基和β-羟基）、它们的乙酰甲酯及其2,3-脱氢衍生物的电子碰撞诱导碎片化。观察到的过程中不常见的特征包括乙酸甲酯以及C-2和C-3烃的排出，还有一些新颖的重排。质荷比为131的离子在许多碎片化序列中作为末端出现。
