Molecular Characterization Team
Team Head
Hiroyuki KOSHINO (D.Agr.)
Our team provides diverse research support for molecular characterization. We develop new methods and technologies for structural elucidation of new organic compounds that are important in chemistry and related scientific fields such as chemical biology research. We maintain and operate MS, NMR, and CD instruments for researchers. Our research supporting activities include training on the machine use, technical assistance, acquisition of spectral data, and data analysis for structural determination of organic compounds. We support and collaborate with many research groups and continue to improve our capability and methodology for structural determination by spectroscopic analysis together with organic synthesis.
