## Abstract ^15^N NMR spectral data for 3‐substituted (chloro, bromo, acetyl, carboxy, carboethoxy, methylsulfanyl, methylsulfinyl, __N,N__‐dimethylsulfamoyl, nitro) 4(1__H__)‐quinolinones and their 1‐methyl derivatives are presented. Copyright © 2003 John Wiley & Sons, Ltd.
Electron impact induced fragmentation of some l-(6'-substituted-4'-methyl-2'-quinolyl)hylpyrazol-5-ols follows a route where the pyrazole moiety is preferentially cleaved with successive losses of two moieties of 41 u. High-resolution measurements have established that the first loss is due to the C
