Abstract
Theoretical computations were carried out on the molecular complex between methanol and carbon dioxide. These calculations explain the broadening of the 15  $\mu$m spectral feature observed in interstellar ices. This feature is assigned to the bending of C-O of the carbon dioxide and we confirm that the broadening is compatible with methanol interactions of the electron donor acceptor type. Extra interactions are also investigated and can be implied in the broadening.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
