质谱分析求解

From the Mass Spectra below,what functional group does thiscompound have? 
What is the mass of this molecule?(assume all of thecompound spectra is present)
实在是分析不出来,

Answer 1

推测结构是三氯乙烷,我查到NIST里是1,1,1-三氯乙烷.3个Cl的同位素比较明显 m/z 61含一个Cl,m/z 97含2个Cl,m/z 117含3个Cl,m/z 26 C2H2,m/z 82 CCl2.
三氯乙烷 分子式 C2H3Cl3 相对分子量132.
