Re: CCL:absorbance spectra or colored compound prediction



For a great review see the chapter by Stefan Grimme in Vol 20 of Reviews in Computational Chemistry, and the references therein. This may be the best review available on the subject for ab initio based methods.

 Hi
 There are numerous examples of TDDFT producing unrealistic and
 unexpected results on various systems.  The system itselt should be well
 studied both experimentally and theoretically before extracting deep
 information from TDDFT results.
 Molecular Physics, Vol. 103, No. 6, 2005, 1057.
 should provide one example of the analysis of TDDFT performance.

 Hi Fred,
 depending on the size of your system my choice would be Time Dependent Density
 Functional Methods or ZINDO/S. The first one is quite accurate but it is more
 expensive, while ZINDO/S is semi-empirical and faster but with lower accuracy.
 Hope it helps,
 Oscar

 Asunto: CCL:absorbance spectra or colored compound prediction
 Dear colleagues,
 I am looking for a method to predict colored compounds or their absorbance
 spectra in UV-vis.
 Thanks for your suggestions
 Fred
