First, the researchers used a short laser pulse about 200 nanometers in wavelength to excite ammonia molecules. This pump ...

Two guys — Stern and Gerlach — did an experiment in 1922. They wanted to measure magnetism caused by electron orbits. At the time, they didn’t know about particles having angular momentum due to spin.

For the first time, scientists visualized how electrons behave during a chemical reaction, which could help reduce unwanted byproducts in future chemistry. When you purchase through links on our site, ...

One of the rarest and most mysterious elements in the periodic table has finally given up some crucial chemical secrets, eight decades after its discovery. Researchers at Oak Ridge National Laboratory ...

I primarily teach General Chemistry to non-chemistry majors and Writing Intensive Physical Chemistry labs for chemistry majors. 1. How do you use AI in your teaching, and what are your favorite ...
