The Journal of Molecular Spectroscopy presents experimental and theoretical articles on all subjects relevant to molecular spectroscopy and its modern applications. An international medium for the publication of some of the most significant research in the field, the Journal of Molecular Spectroscopy is an invaluable resource for astrophysicists, chemists, physicists, engineers, and others involved in molecular spectroscopy research and practice. Feature Articles: It is planned to have several peer reviewed Feature articles in the Journal of Molecular Spectroscopy each year. These articles will overview areas of particular significance in molecular spectroscopy. They may review and consolidate an area of theoretical development or a collection of experimental data, in each case offering some new insights. The articles may also summarize the present status of a rapidly developing and/or evolving field. All the articles should serve as introductions to areas of spectroscopy other than one's specialty and should be particularly valuable to students entering the field.Feature articles will be solicited by invitation of the Editor . However, the Editor invites suggestions, with a reasonable level of detail, about topics that could be of interest. Self suggestions by potential authors are particularly encouraged.
