The Intro to Spectroscopy (UV–Vis, IR) – Real World Applications section demonstrates how spectroscopic techniques are used in everyday life, industry, medicine, environment, and research laboratories. This module is designed for Class 11–12 students and undergraduate learners, helping them connect spectroscopy concepts with real-world chemical analysis.
In this section, you will explore:
Pharmaceutical applications – drug identification, purity testing, and quality control
Environmental monitoring – detection of pollutants in air and water using UV–Vis methods
Food and beverage analysis – color measurement, additive detection, and quality assessment
Medical and biochemical uses – analysis of proteins, nucleic acids, and blood components (introductory)
Industrial quality control – monitoring raw materials and finished products
Forensic science applications – identification of unknown substances and trace analysis
Polymer and material analysis – functional group confirmation using IR spectroscopy
Academic and research applications – reaction monitoring and compound characterization
NCERT- and UG-aligned explanations, supported by real spectra examples, case scenarios, application-based MCQs, and numerical problems
The content is structured to enhance practical understanding, improve application-based reasoning, and prepare students for case-based and real-world exam questions.
Develop a practical and meaningful understanding of UV–Vis and IR spectroscopy by exploring their real-world applications, strengthening both academic learning and scientific awareness.
