Hi everyone, Prof. Helgaker (yes, one of the authors of the purple book on Molecular Electronic Structure theory) is visiting for Theochem next week. People interested in meeting him, or having lunch or dinner with him, please slack me. He will be presenting his talk on Wednesday at MIT, regular time (4:15 Room 4-163). Find his abstract attached. Cheers, Jhonathan. -- Jonathan Romero Fontalvo *Ph.D. Student in Chemical Physics* *Harvard University* Website: https://sites.google.com/site/jonathanromeroswebsite/
