Can anyone provide me (a literature reference is ok) with information on the geometry of this molecule in the following situations : 1) isolated molecule 2) molecule in 1-propanol (at different temperatures) 3) molecule in a nonpolar solvent 4) molecule in in PMMA (solid state) Thanking you in advance, I will be glad to provide a summary to the list. Yours sincerely, ========================================================================== Yves Verbandt tel. 32-2-641.36.13 Applied Physics Dept. fax. 34.50 Vrije Universiteit Brussel email yverband@vnet3.vub.ac.be Pleinlaan 2, 1050 Brussel, BELGIUM yverband@vub.ac.be ==========================================================================
