Introduction Spectroscopy is a powerful analytical technique that involves the interaction of matter with electromagnetic radiation. This lecture will explore the fundamental principles of spectroscopy and its diverse applications in various scientific disciplines. Learning Objectives By the end of this lecture, you should be able to: Understand the fundamental principles of spectroscopy. Describe the types of spectroscopic techniques. Recognize the significance and applications of spectroscopy in different fields. Principles of Spectroscopy 1. Electromagnetic Radiation: Spectroscopy involves the interaction between matter (atoms, molecules, or solids) and electromagnetic radiation, such as visible light, ultraviolet (UV), infrared (IR), and X-rays. 2. Absorption and Emission: Matter can absorb energy from radiation, leading to electronic transitions within the material. Conversely, excited states can emit energy as radiation. 3. Spectral Analysis: Spectroscopic techniques analyze the ...

 Units of R adioisotope dating techniques In radioisotope dating techniques, several units are commonly used to express various measurements related to radioactive decay and the determination of ages. Here are some of the key units and their meanings: Activity (Becquerel, Bq) : Definition : The activity of a radioactive substance measures the rate at which it undergoes radioactive decay. It is defined as one radioactive decay per second. Unit : Becquerel (Bq). Symbol : Bq. Half-Life (years) : Definition : The half-life of a radioactive isotope is the time it takes for half of a sample of that isotope to decay. It is a measure of the rate of radioactive decay. Unit : Years (or other time units, depending on the context). Specific Activity (Bq/g or Bq/mol) : Definition : Specific activity is a measure of the radioactivity per unit mass (Bq/gram) or per mole (Bq/mol) of a substance. It provides information about the concentration of radioactive atoms. Units : Becquerels per gram (Bq/g...
