CHEM-412 Advanced Spectroscopy-I (Minor)

COURSE OUTLINE FALL 2020

Course Tittle: ADVANCED SPECTROSCOPY – I (MINOR)

Course Code: CHEM-412

Credit Hours: (3+1)

Instructor: MUHAMMAD SHER

DESCRIPTION& OBJECTIVES

Advance spectroscopic techniques including in this course are very important regarding the identification and characterization of newly synthesized or isolated chemical compounds. These courses develop the skill in the student to understand the instrumentation of UV/Visible spectrophotometer, Atomic Absorption spectrophotometer and Atomic Emission spectrometer. It also develops the skill in the student to interpret the UV/Visible spectra of various compounds for structure determinations. Atomic Absorption and Emission spectroscopy is another major topic in this course, which in turn enable the students to identify and quantify the various metals present in samples. UV/Visible and atomic spectroscopy has number of applications in the various fields of research.
