摘要

The UV and polarized IR spectra of argon matrix isolated cyclobutadiene and its Id-, 1, 2-d2-, 1, 4-d2-, I%", l, 2-W2-, and I, I-W2-1abeled derivatives are reported. Above 250 nm, the UV spectrum contains no peaks with an extinction coefficient larger than 10 L Ml cm-l, but a weak absorption tail extends throughout the UV region. The absorption rises abruptly below 250 nm. The IR peak positions mostly agree with previous reports where these are ...
