Biography

He does not have cable, and he subscribes to The Atlantic Monthly. He owns a 1983 Goldwing motorcycle, and his great uncle hid Jews in his barn in the Netherlands during WWII. His favorite molecule is water.

"I have been interested in chemistry since 1960,” said Calvin professor of chemistry Roger DeKock , “What is that? 48 years? … I want to know at the molecular level, ‘How does that happen?’”

DeKock’s current research has brought him to that level, where he works with his favorite molecule. “I started to get into water during my ’03-’04 sabbatical in Calgary,” DeKock said. “Part of my research there dealt with water molecules: hydrogen atoms in aqueous systems can be very mobile.”

Before DeKock earned Fulbright and NATO scholarships for his research, before his life’s work brought him into contact with prominent social conflicts of the 20th century began, he was a growing boy in Prairie City, Iowa where, “the prairie was there; the city was not,” he remarked. “I was third in my grade school class; there were five of us.”

When it came time for college, DeKock followed the path forged by his older brother: a degree in chemistry from Calvin College. “I thought he was above me,” he said of his model.

Academic interests

In our research we investigate the structures and relative energies of organometallic complexes that have different placement of hydrogen atoms. In particular we are interested in heterobimetallic complexes (Rh, Os) wherein the hydrogen atom migrates from a metal atom to a bridging methylene ligand. This is part of a larger project that investigates C-H bond activation.

Detailed Research Information

We model molecules using the tools of computational chemistry. Some of our chemical projects are:

1) Hydrogen atom migration in organometallic complexes.

2) Relative energy of molecular and ionic forms of NH3(H2O)7. research image

3) We are examining methods to extract "effective" nuclear charges from atomic ionization energies.
