Mass spectrometry of tropylium halides

✍ Georg Hvistendahl; Kjell Undheim; Peter Gyöösi 📂 Article 📅 1973 🏛 John Wiley and Sons 🌐 English ⚖ 143 KB

## Abstract The base peak and highest mass number in the spectra of tropylium iodide and bromide corresponds to the mass of the cation. Both appearance potential (AP) measurements and the fragmentation pattern strongly indicate that the gaseous species present is the tropylium radical. Rediction to

The mass spectrum of mevalonolactone

✍ R. T. Gray 📂 Article 📅 1974 🏛 John Wiley and Sons 🌐 English ⚖ 176 KB

## Abstract The principal fragmentation pathways of mevalonolactone are initiated by cleavage α to the hydroxyl function. Each major route has been delineated by using isotopic labelling and metastable analysis. A knowledge of this fragmentation pattern is useful for the calculation of isotopic pur

The most prominent ion in the mass spectra of C,F,CH,X (X = H, Br, CH:CH,, COCI, and CH,C6F5) is C,F5H2+, formulated as the pentafluorotropylium cation. This ion is also found, in an amount comparable to the parent ion, in the spectrum of (CBF5)\*CH2. The heptafluorotropylium cation is found similar

The mass spectrum of isopropyl o-toluate

✍ Susumu Tajima; Tamae Yanagisawa; Tadashige Azami; Yoshio Niwa; Toshikazu Tsuchiy 📂 Article 📅 1981 🏛 John Wiley and Sons 🌐 English ⚖ 386 KB

## Abstract The formation of an [M + 1]^+^ ion and the fragmentation of isopropyl __o__‐toluate have been investigated by the deuterium labelling technique and kinetic energy release measurements. The hydrogen atom involved in the [M + 1]^+^ ion formation does not originate from a specific part of
