Abstract

Six alkyl alcohols were studied using thermospray mass Spectrometry. Whereas the dominant ion in the spectrum up to a repeller potential of 120 V was [M + NH~4~]^+^, above that potential [M + H]^+^ and fragment ions appeared. The fragments observed were largely due to hydrogen release from alkyl ions ([C~n~H~2__n__+1~]^+^ – H2 β†’ [C~n~H~2__n__‐1~]^+^) and loss of water or some other stable molecule from the same species. The results are compared with those from ionization of the same alcohols under electron impact and photoionization conditions and with results obtained for methanol under thermospray conditions.
