Course Code: RM-572 Course Title: Analytical Techniques

Class: MS Textile Engineering, Semester: 2nd

Total Marks: 10 You are being provided with forty set of problems. Each problem consists of different

spectra (IR, 1H-NMR, 13C-NMR, Mass etc).

Give assignments to every peak in the spectra and finally deduce the actual structure of

the said compound and submit the assignment within the due date positively.
