We report the first observation of the laser-induced fluorescence excitation spectrum of the A^(1)A"(000)-X^(1)A(010)vibronic band of HCF with the technique of molecular beams.
Aggregation behaviors of 1-alkanoylperylenes (Pe-n, n = 4, 8,12) driven by hydrophobic-lipophilic interaction (HLI) have been investigated in dioxane (DX )-H2O binary aquiorgano solvents by means of fluorescence spect...Aggregation behaviors of 1-alkanoylperylenes (Pe-n, n = 4, 8,12) driven by hydrophobic-lipophilic interaction (HLI) have been investigated in dioxane (DX )-H2O binary aquiorgano solvents by means of fluorescence spectroscopy. A novel empirical equation, which rationalizes CAgC (critical aggregate concentration) dependence of the aggregates both on the chain-length of the substituent alkyl group and on the solvent aggregating power (SAgP) for Pe-n, has been derived.展开更多

It is a new trend of researches in carbene chemistry to study the chemical reactions of electronically excited carbenes, of which the results are bound to promote applications. of carbene reactions in organic chemistry. Thus the spectroscopic studies of carbenes are significant for carving out a new path of researches in carbene chemistry.展开更多
