This doctoral-level course provides students with advanced knowledge and practical understanding of modern spectroscopic techniques, with emphasis on instrumentation, data interpretation for structural elucidation, and applications in pharmaceutical, chemical, and biological sciences. The course integrates theoretical foundations with practical case studies to demonstrate the role of spectroscopy in research, development, and quality control, particularly in the pharmaceutical field. By the end of the course, students will be able to critically interpret spectral data, apply these techniques to pharmaceutical and biomedical research, and design studies that utilize spectroscopy as a core analytical tool.
