Scientific Computing: Computational Chemistry

For me, anything computational is unexplored frontier. I've never studied computational physics, chemistry, or even science for that matter. The algorithms and models scare the heck out of me, but I guess this blog post will help me with my understanding and stare computational science right in the figurative eye.

Computational chemistry is the science of running computer simulations to help solve chemical problems. So rather than mixing chemical A with chemical B to see what happens, you could theoretically use the computer simulation and get the exact same result. Where the mind boggling part comes in is that a computational chemist must have a vast knowledge of both chemistry and computer science. Finals are right around the corner and thinking about more schooling makes me shudder.

The holy grail for all computational chemists is to create a formula or program that can simulate any and all chemical reactions and behaviors. There are two branches of computational chemistry. First is molecular mechanics and dynamics base which is based on classic mechanics and incorporating parameters from different experiments or theoretical methods. The second branch is called computational quantum chemistry which, to my knowledge, uses quantum mechanics to model individual atoms and molecules.

One of the main benefits of using computational chemistry versus doing lab work is reducing the cost. Chemicals aren't cheap and using computers to do it rather than actual lab equipment saves costs, plain and simple. It also helps with the safety of chemists when dealing with volatile or toxic chemicals. One of the great benefits of computational chemistry is that if the formulas and code are correct, you get a very accurate result with no varying factors such as contamination, wavering temperatures, etc.


All in all computational chemistry is actually a very interesting subject. The ability to test everything on a computer would be an extraordinary tool for chemists to use and would therefore further chemists knowledge in the field.

  1. hi Steve, this is a great post. I totally agree how scientific computing helps develop modern research in science, particularly chemistry. It surely reduces the lab work and hence the cost. Last year, I used computer program to simulate biological pathways so I know how effective this method can be. I agree with you that wet lab results should be tested on computer for more accurate result and less cost. This is a great post

  2. How do we do, Steve? This is my first time to comment on your blog. This is a detailed, well researched posting. You researched about the computational chemistry, which I also find interesting. I agree with you that researchers wouldn't finish fruitful experiments without using computational chemistry. I think it's very reasonable that complex computation is done by computers not by humans by hands.

  3. Great article! You are the first person that I have read that decided to conquer the chemical computation topic. I did not really know how chemical computation was conducted so I was glad to learn something. I feel like this is a good start for someone trying to learn more about the topic. I would have liked to see a few examples of how this type of computing has actually effected chemical analysis. I appreciate that you added the links on the end for more information. Great work.
