Structure, Configurational Stability and Stereodynamics in Solution
During this work, Vito Capriati, Saverio Florio and colleagues at the University of Bari in Italy used in situ Infrared (IR) and Nuclear Magnetic Resonance (NMR) spectroscopy together to give a better insight into the stability of lithium salt and to ultimately answer the question:

“Is the lithium salt more like an organolithium or is it more like an azaenolate?”

How Has Organic Chemistry Changed in Academia?

Traditionally, organic chemistry students have been instructed to analyze reactions using standard offline analytical methods, such as High-Performance Liquid Chromatography (HPLC), Nuclear Magnetic Resonance (NMR) Spectroscopy, and Gas Chromatography (GC).

How To Study Chemistry Under Actual Reaction Conditions

Traditional offline methods to analyze reaction chemistry, such as High-Performance Liquid Chromatography (HPLC), Nuclear Magnetic Resonance (NMR) Spectroscopy, and Gas Chromatography (GC), share a common problem: when a sample is removed for analysis, it may be altered or compromised resulting in significant analytical errors. The solution for this is Continue reading
