We have obtained low-resolution mass spectra under as uniform conditions as possible at 20 and 70 eV for the following ribonucleosides: cytidine, uridine, adenosine, 5-hydroxymethyluridine, 2-methyladenosine, 2′-O-methyladenosine, isoguanosine, xanthosine, 2′-O-methylguanosine, N2,N2-dimethylguanosine, N6-(3-methyl-2-butenyl)adenosine, N6-(3-methyl-3-butenyl)adenosine, ribosylzeatin, N6-(3-hydroxy-3-methyl-butyl)adenosine, ribosyldihydrozeatin, and N6-(3-methyl-2-butenyl)-2-methylthioadenosine. All these ribonucleosides are components, or possible components, of tRNA. The spectra are intended as reference spectra for the structural confirmation of known nucleosides from tRNA and for the identification of unknown, modified nucleosides by comparison of their fragmentation pattern with those already recorded.
