Abstract

For the first time a secondary ion mass spectrum of diethyl ether was obtained at low temperature. The spectrum recording became possible by carefully selecting the range of experimental conditions for the production of a cluster-type spectrum. This range is specified by the threshold for spectrum appearance above the melting temperature of the frozen sample and a fairly short time span of existence of the liquid estimated as only a few minutes. The latter necessitates rather rapid spectrum detection. In practice, about 1 min was available for recording of the cluster-type spectra. The secondary emission mass spectrum of diethyl ether appeared to be rich in peaks: along with abundant protonated clusters Mn · H+ (n = 1-12), unusually intense [Mn - H]+ and weaker Mn+• peaks were present accompanied by several sets of fragmented clusters, [Mn - 15]+, [Mn - 29]+, [Mn - 27]+, [Mn - 45]+, and monohydrates, Mn · H2O · H+. The analysis of all the peaks showed that the pattern of fragment clusters is qualitatively similar to the pattern of fragmentation of the diethyl ether molecular ion under high-energy electron impact. The general features of the behaviour of diethyl ether under low-temperature mass spectrometric conditions were similar to those observed earlier for some other organic solvents.
