It does not seem, however, that organic chemists were much worried about barriers to rotation in organic molecules in general at that time because there was no technique available to demonstrate the phenomenon experimentally. ↗

We may say that a basic substance is one which has a lone pair of electrons which may be used to complete the stable group of another atom, and that an acid is one which can employ a lone pair from another molecule in completing the stable group of one of its own atoms. ↗

One day I discovered that one could get the barrier to internal rotation in ethane approximately right using this method. This was the beginning of my work on organic molecules. ↗

When you look more generally at life on Earth, you find that it is all the same kind of life. There are not many different kinds; there's only one kind. It uses about fifty fundamental biological building blocks, organic molecules. ↗

I am saddened by how people treat one another and how we are so shut off from one another and how we judge one another, when the truth is, we are all one connected thing. We are all from the same exact molecules. ↗

I will never use a substitute for butter. Margarine is one molecule away from eating plastic. If I'm going to eat that type of food, it's going to be the real deal. ↗

This simple idea served to provide information on the geometrical shape of reacting molecules, and I was able to make the role of the frontier orbitals in chemical reactions more distinct through visualization, by drawing their diagrams. ↗

This work made me more and more interested in biological matter, and I decided that I really wanted to work on the X-ray analysis of biological molecules. ↗

A composer is a guy who goes around forcing his will on unsuspecting air molecules, often with the assistance of unsuspecting musicians. ↗

The magnitude of the atomic weight determines the character of the element, just as the magnitude of the molecule determines the character of a compound body. ↗
