Abstract
Recent work in our laboratory has led to the first size-selective infrared spectra of neutral Li(NH$_{3}$)$_{\textit{n}}$ clusters. Here we report on new work extending these studies to mixed cluster species, where ammonia derivatives such as methylamine (MA) replace some of the ammonia molecules. Spectra recorded using mass-selective IR depletion spectroscopy will be reported for Li(MA)$_{\textit{m}}$(NH$_{3}$)$_{\textit{n}}$, with the emphasis on \textit{n} $+$ \textit{m} $=$ 4 clusters. The impact of replacing NH$_{3}$ with bulkier ligands on the solvent structure will be described. In addition the IR spectrum of the smaller cluster Li(MA)(NH$_{3}$) will be reported for the first time.
