Progressions

Progressions has returned! After a long hiatus, Progressions is returning with a strong focus on integrating new content as well as promoting PLTL. In particular, we are interested in the revolution in our understanding of chemical bonding, as represented in works such as "Valency and Bonding" by Weinhold & Landis. The upcoming Fall 2019 edition will be a short course in the Valence Bond, from Pauling to Natural Bond Orbitals.

Progressions is now available as a printable Google Document.

The old Progressions are available as pdf files (see below)
