摘要：
Doubly charged methanol ions formed by photoionization at vacuum ultraviolet wavelengths decay mainly by fast charge separation along a large number of pathways. The major reactions involve sequential, not concerted processes, with little hydrogen scrambling. The species CH2OH2+ and CHOH2+ are observed as relatively long-lived intermediates with mean lifetimes between 10 and 100 ns.
