9315268 Herbig Studies of the Diffuse Interstellar Bands. The enigma of the Diffuse Interstellar Bands (DIBs) remains one of the outstanding problems of astronomical spectroscopy. Clearly their carriers are fairly common constituents of the interstellar medium yet remain unidentified despite some 60 years of effort. Dr. Herbig, at the University of Hawaii, will continue his research into the nature of DIBs. Specifically he will investigate whether polycarbon or chlorin molecules may be responsible for some DIBs. Efforts will also be made to determine if sodium atoms trapped in carbon 60 cages produce a DIB near 1.03 micrometers wavelength, whether DIBs can be detected in the ejected envelopes of carbon stars by spectroscopy of their companions, and whether there is a detectable enhancement of the DIBs in light scattered off the dust of reflection nebulae.

小行星9315268 星际弥散带的研究。 星际弥散带之谜一直是天文光谱学的突出问题之一。 显然，它们的载体是星际介质中相当常见的成分，尽管经过了大约60年的努力，但仍然无法识别。 夏威夷大学的赫比格博士将继续研究DIB的性质。 具体来说，他将调查聚碳或氯分子是否可能是某些DIB的原因。 还将努力确定被困在碳60笼中的钠原子是否会产生波长接近1.03微米的DIB，是否可以通过其同伴的光谱学在碳星的喷射包层中检测到DIB，以及反射星云尘埃散射的光中是否有可检测到的DIB增强。
