Photoionization Mass Spectrometry and Photoelectron-Photoion Coincidence (PEPICO) Spectroscopy Studies of Select Biofuel Molecules
… discuss the photoelectron-photoion coincidence (PEPICO) spectroscopy of two biofuel additives (GVL and mesitylene). This technique is used to measure various thermodynamic quantities, such as heats of formation, entropies of activation, and bond strengths. In addition, dissociation rates will …

A tale of two small oxygenated molecules as told by photoelectron photoion coincidence spectroscopy
<p>Photoelectron Photoion Coincidence (PEPICO) Spectroscopy studies on two small oxygenated species are presented here. Diethyl Ether (Et2O) and Acetic Anhydride (AcOAc) were chosen because of their and their fragments' relevance to combustion chemistry. The Imaging PEPICO (iPEPICO) experiment at …
