  • B NMR Spectroscopy 
    Perera, K. Sarath D. (Institute of chemistry Ceylon, 2023-09)
    Boron hydrides are known as electron deficient compounds. There are two NMR active isotopes (e.g., 10B and 11B). Boron-11 NMR spectroscopy is widely used to find out molecular structures and exchange processes of boron ...
  • Infrared Spectroscopy 
    Perera, K.Sarath.D. (Institute of Chemistry Ceylon, 2022-06)
    The energy of most of the molecular vibrations falls into the infrared region (4000 - 400 cm-1) of the electromagnetic spectrum. Infrared (IR) or vibrational spectroscopy is used by organic chemists to: (i) identify functional ...
  • UV-visible Spectroscopy 
    Perera, K.Sarath.D (Institute of Chemistry Ceylon, 2022-06)
    Molecules have different energy states: electronic, vibrational, rotational, and nuclear. Quantized energy is responsible for each transition (e.g., rotational - microwaves, infrared - vibrational) within the ...
  • Versatility of Raman Spectroscopy as an Analytical Tool for Chemists 
    Abeyasingh, Neranga; Gunewardene, Siyath; Jayaweera, Hiran (Institute of Chemistry Ceylon, 2024-01)
    Often used as a tool in analytical chemistry, Raman spectroscopy is a highly utilized non-destructive vibrational spectroscopic technique. Incident light interacts with the molecules, and the inelastically scattered ...
