Stony Brook的核化学研究集中在重离子束引起的反应上。光束是从位于石溪，伯克利，芝加哥，密歇根州和法文的加速器获得的。反应产生非常热且快速旋转的原子核，通过观察所发射的粒子和碎片进行研究。它们的能量和发射角度允许重建热发射核的性质及其产生机理。同位素化学处理物质的物理和化学性质的细微差异，这些细微差异源于元素同位素的质量差异。尽管影响很小，但可以高精度测量。通常，这些效应是量子效应，同位素效应的测量已被证明是研究分子和分子间力的独特方法。同位素效应研究已应用于化学物理学，有机化学和生物化学，地球化
The Department of Chemistry, within the College of Arts and Sciences, offers courses of study leading to the degrees of Master of Arts in Teaching Chemistry, Master of Science, and Doctor of Philosophy. Students in the M.A.T. program must register through the School of Professional Development. A student in the Ph.D. program may choose dissertation research in any one of the diverse areas of chemistry represented by the interests of the program faculty, or may choose an interdisciplinary topic under the guidance of a faculty member in another program. Coordinated activities exist with several programs, and include optional concentrations in chemical physics and chemical biology. <br><br>Nuclear chemistry research at Stony Brook has focused on reactions induced by heavy ion beams. Beams are obtained from accelerators located at Stony Brook, Berkeley, Chicago, Michigan, and France. The reactions produce very hot and rapidly rotating atomic nuclei that are studied by observation of particles and fragments that are emitted. Their energies and angles of emission allow for a reconstruction of the properties of the hot emitting nuclei and the mechanism of their production. Isotope chemistry deals with the small differences in physical and chemical properties of matter that have their origin in the mass difference of isotopes of an element. Although the effects are small, they can be measured with high precision. In general, the effects are quantum effects, and measurement of isotope effects has proven to be a unique method for the study of molecular and intermolecular forces. Isotope effect studies have found application in chemical physics, organic chemistry and biochemistry, geochemistry, and anthropology. Practical applications are found in isotope separation processes. Our present efforts are concentrated on the systematization of isotope chemistry.
