How to calculate the Delta G of solvation? This is a question that I get a lot in this blog, so it is about time I wrote a (mini)post on it, and at the same time put an end to this posting drought which has lasted for quite a few months due to a lot of pending work with which I’ve had to catch up. Therefore, this is another post in the series of SCRF calculations that are so popular in this blog.

For over a decade these meetings have gathered theoretical chemists every year to share and comment their current work and to also give students the opportunity to interact with experienced researchers, some of which in turn were even students of Prof. Robert Parr, Prof. Richard Bader or Prof. Per Olov Löwdin. This year the Mexican Meeting on Theoretical Physical Chemistry took place last weekend in Toluca, where CCIQS is located.

Last spring I was invited by The State Council for Science and Technology (COMECyT) to be part of the jury in the 5th Mexican Science and Engineering Fair and now we just had the finals here in Toluca. For the first part of this competition several projects were evaluated in their originality and relevance as well as their feasibility.

A couple of months ago, maybe a little bit more, I got the news that the project I submitted to the National Council for Science and Technology (CONACyT) was approved! Now we only have to wait for the money to actually show up and that might take a while – a long while!

If a mind is a terrible thing to waste, then wasting a collective mind is an even more terrible thing. During the past weekend the library at the institute of chemistry suffered a flood caused by a broken pipe just above it, which incidentally happens to be the lab were I used to work as an undergrad student. When it comes to scientific journals, our institute still relies a lot on paper issues for the oldest numbers;

This morning at around 9 AM, I guess, this little blog of mine reached a significant milestone: It reached 100,000 visitors! The blog started about 3.5 years ago when I was still living in Romania working at the lab of the late Prof. Dr. Ioan Silaghi-Dumitrescu.

I don’t know why I haven’t written about the Local Bond Order (LBO) before! And a few days ago when I thought about it my immediate reaction was to shy away from it since it would constitute a blatant self-promotion attempt; but hell! this is my blog! A place I’ve created for my blatant self-promotion! So without further ado, I hereby present to you one of my own original contributions to Theoretical Chemistry.

Calculating both Polarizability and the Hyperpolarizability in Gaussian is actually very easy and straightforward. However, interpreting the results requires a deeper understanding of the underlying physics of such phenomena. Herein I will try to describe the most common procedures for calculating both quantities in Gaussian09 and the way to interpret the results;

I was first introduced to Bradbury’s writing in 1989 during my first year in junior high school (here in Mexico that is the 7th grade; I was eleven years old then) by my literature teacher Ángel Molina-Aja at LOGOS School, a progressive institution in southern Mexico City;

A new paper has been published and that is always good news.

We recently got notice of our paper being accepted for publication in the Journal of Inclusion Phenomena and Macrocyclic Chemistry . We are very pleased with this news! The paper’s title is “ Ab initio calculations of electronic interactions in inclusion complexes of calix- and thiacalix[n]arenes and block s cations ” and is being co-authored by Dr. Petronela Petrar, Prof. Dr. Kunsagi-Mate Sandor, the late Prof.
