Absfract-Original mass spectra of uracil and thymine derivatives are presented with the corresponding fragmentation schemes. In the first series of spectra, the fragmentations of thymine derivatives, including 14C-2-thymine, dimers, and bromo thymines, confirm the basic retro Diels-Alder mechanism.
