论文摘要
此处考虑的是五个漫射的星际频段（DIB）之间的相互关系：$λλ$ 5545、6113、6196、6445和6614Å。两个dibs（$λ$ 6196和$λ$6614Å）彼此之间也已经相互关联。他们与另外三个较弱的乐队的关系首次研究。为了完成此任务，使用高分辨率光谱（$λ/δλ$ \ $ \ $ 100,000），使用高信噪比（S/N）为54热O-B恒星，使用了0.12-1.45 mag。对测得的等效宽度的分析已允许建立线性依赖性并评估这五个DIB的强度之间的线性相关系数高达0.968-0.988。这种相关程度可能表明它们的共同起源。在这些DIB之间发现的波数中的几个间距对应于某些PAH中的振动转变能量，导致IR排放$λλ$ 16.4、11.3、7.7、6.2和3.3 $ $ m。
Considered here is the interrelation between five diffuse interstellar bands (DIBs): $λλ$ 5545, 6113, 6196, 6445 and 6614 Å. Two DIBs ($λ$ 6196 and $λ$ 6614 Å) have already been known as well correlated with each other; their relation with three other, weaker bands, was investigated for the first time. To accomplish this task high-resolution spectra ($λ/Δλ$ $\approx$ 100,000) with high signal-to-noise ratio (S/N) of 54 hot O -- B stars with reddening 0.12 -- 1.45 mag were used. Analysis of measured equivalent widths has allowed to establish linear dependencies and evaluate linear correlation coefficients as high as 0.968 -- 0.988 between the intensities of these five DIBs. Such a degree of correlation may indicate their common origin. Several spacings in wavenumbers found between these DIBs correspond to the energies of vibrational transitions in some PAHs resulting in IR emissions at $λλ$ 16.4, 11.3, 7.7, 6.2 and 3.3 $μ$m.
