Physical organic chemistry refers to the study of the relationship between the structure of organic molecules and their electronic and physical properties. Some potential synonyms for this field of study might include molecular physics, chemical physics, or molecular spectroscopy. The field encompasses a wide range of topics, from measuring the energy required for chemical reactions to studying the effects of temperature and pressure on chemical systems. Additionally, physical organic chemists also often use sophisticated computational models and computer simulations to understand the behavior of molecules at the molecular level. Overall, physical organic chemistry is a diverse and rapidly evolving field that offers many exciting new avenues for researchers to explore.
