摘要
利用高分辨率的DMS-300UV-Vis光度计,于乙醇溶液中得到了萘的β带的精细光谱。给出骈苯系β带的3条同系线,回归出β_I,β_(II)的■与同系序数n的定量关系,其γ分别为0.9999,1.0000,并证明这是一组邻同系峰。同时预测了骈苯系β带中一些未知峰的可能波长。
The fine spectra of naphthalene was measured in ethyl alcohol solution on the DMS-300UV-Vis spectrophotometer. The three homologous lines of β band of aromatic hydrocarbons compounds were gaven. As so as, the quantititive relationship of ■and n in β1 and β1 lines were gained, and the correlation cofficient of them are 0. 9999 and 1. 0000 respcetively. The accuracy of β1 increased three tames to the former result. That the grup of peak belongs to the neighbor homologous peaks was proved. For a series of unknown peaks in β-band of aromatic hydrocarbons, the wave length would be predictived.
