Mass Spectrometric Investigation of 2-Methoxyethanol and 2-Ethoxyethanol Clusters: Magic Numbers and Structural Implications
Abstract
In this paper we present the results of our mass spectrometric investigations for van der Waals clusters of 2-methoxyethanol and 2- ethoxyethanol. The cluster mass spectra were acquired for a variety of expansion conditions and electron energies. The protonated alkoxyethanol cluster ions (AE)nH(+) form the dominant cluster ion series. A number of fragment ions, that may arise from an unprotonated and/or a protonated alkoxyethanol molecular ion, were solvated by additional alkoxyethanol molecules. The (AE)n(H20)mH(+) ions were observed with significant intensities only for n >/= 5 in neat as well as mixed alkoxyethanol/water expansions. It was also found that (AE) n (H20)m H(+) cluster ions which satisfy the condition n = 2 (m + 2), for m = 1 and 2, have enhanced ion intensities. The various models that may explain the behavior of (AE)n(H20)mH(+) are discussed.
