  • 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 ...
  • Chemical Constituents of the Golden Spice – Turmeric 
    Perera, K. Sarath D. (Institute of chemistry Ceylon, 2023-06)
    Coordinatively unsaturated metal centers may interact with a C-H bond of a coordinated ligand and then undergo C-H bond activation or fission to form metallacycles.
  • Cyclic Voltammetry 
    Perera, K. Sarath D. (Institute of chemistry Ceylon, 2024-01)
    Cyclic voltammetry (CV) is used extensively by electrochemists to obtain the potential at which the chemical processes occur, and to obtain information about coupled homogeneous chemical reactions or the role of ...
  • Defense and Destruction: Insight of Chemical-based Weapons 
    Perera, K. Sarath D. (Institute of chemistry Ceylon, 2023-06)
    Coordinatively unsaturated metal centers may interact with a C-H bond of a coordinated ligand and then undergo C-H bond activation or fission to form metallacycles.
  • Electrophilic attack on Coordinated Ligands 
    Perera, K. Sarath D. (Institute of chemistry Ceylon, 2024-01)
    Organometallic complexes have at least one organic group and they can undergo various types of reactions. Incoming electrophile may react with or attack on either the metal centre or on one of the coordinated ligands
  • Elements in Biology 
    Perera, K. Sarath D. (Institute of chemistry Ceylon, 2023-09)
    Research findings suggest that eleven elements are predominantly present in all biological systems. However, hydrogen, carbon, oxygen and nitrogen correspond to 99% of the total. Hydrogen constitutes 62.8% of the atoms in ...
  • Introduction to Organometallic Chemistry 
    Perera, K. Sarath D. (Institute of chemistry Ceylon, 2023-09)
    Organometallic chemistry is a branch of coordination chemistry and deals with compounds which have at least one metal-carbon bond. Since metals are more electropositive than carbon it is considered that the metal-carbon ...
  • Stability of Metal Complexes 
    Perera, K. Sarath D. (Institute of chemistry Ceylon, 2024-01)
    A coordination complex of the type [MLx ]n+ is formed when each neutral ligand (L) donates a lone pair of electrons to a metal centre (Mn+). Here, x is the coordination number and n+ is the oxidation number of M. We ...
