Low energy, low temperature mass spectra: I—selected derivatives of n‐octane

The low voltage, low temperature mass spectra of a series of octane derivatives n ‐C 8 H 17 X with X=CH 3 , OH, OCH 3 , NH 2 , NHCH 3 , N(CH 3 ) 2 , CO 2 H, CO 2 CH 3 , CO 2 C 2 H 5 , CHO and COCH 3 are reported and discussed, using arguments involving thermochemistry where appropriate. The structures of these compounds can be uniquely assigned on the basis of such mass spectra.
