You're right, you don't need 90% of what is in the P-chem curriculum, but....

Students often wonder why so much irrelevant material is foisted upon them in their undergraduate courses. P-Chem and calculus often bear the brunt of such criticisms by chemistry majors, but no doubt undergraduates in all majors express similar frustrations and douts. During my seminar, I'll use projects at Dakota Technologies, a high technology business I co-founded in 1993, to show that you can never be quite sure what information you'll need to solve "real-world" problems or when you'll need it. I'll also take advantage of the opportunity to describe a few of my ideas for re-structuring the undergraduate curriculum.

2D Mass Spectroscopy: Mining for Mechanisms of Chemical Bond Fragmentation

My undergraduate research group at Carleton is interested in dissecting the bond breakage half of chemistry when a small gaseous molecule absorbs very high-energy light (X-rays). Simple ideas suggest all bonds would be obliterated at once. In reality, there are a number of concerted and sequential mechanisms that involve early or late ejection of neutral pieces and separation of charged fragments ­ complexity abounds! I will discuss a fancy and intriguing kind of 2D time-of-flight mass spectroscopy that allows us to simultaneously detect 1 electron and 2 positive ion pieces produced from the fragmentation of a single molecule. I will focus on results from C4F8 and piece together a detailed "billiard ball" picture of how molecules fall apart following photo-excitation. Photofragmentation studies can help establish basic mechanistic principles and patterns relevant to more applied systems like the earthıs atmosphere.
