Abstract
A surface structure of submonolayer methanethiol CH₃SH molecularly adsorbed on Cu(100) has been investigated by means of S K-edge SEXAFS and NEXAFS. From the analysis of these spectra, it was revealed that the CH₃SH molecule adsorbs as a methanethiolate (CH₃S^-) with the S-C bond nearly perpendicular to the surface. SEXAFS has clarified that the S atom locates at the fourfold hollow site and the S-C and S-Cu bond distances are, respectively, 1.82±0.02 and 2.29±0.03 Å. Although it was reported that the adsorption of methanethiol induces surface reconstruction on the Cu(111) surface, we have observed neither reconstruction nor large strain ou the Cu(100) surface.

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.
