Out of some +1000 twitter accounts I follow about a quarter are related computational chemistry. The following public list isn’t comprehensive and prone to errors and contains researchers, programmers, students, journals, products and companies who gravitate around the use of in silico methods for the understanding and design of chemical and biochemical compounds.

Sir,
being quite new to #ComputationalChemistry, I would like your opinion on how to check and predict for weak molecular interactions (i.e. hydrogen bond) from #Gaussian09 calculation?
