This playlist consists of all the basic and point-to-point, basic to advanced details related to NMR spectroscopy. This series will be very helpful for all undergraduate, BSc , and postgraduate MSc, students. This will be quite helpful for all the competitive exams like M.Sc entrance, IIT JAM, CSIR NET, GATE SET, and PGT exams related to chemistry. In the very first video I discussed the basic introduction to NMR spectroscopy. As in each type of spectroscopy, electromagnetic radiation plays a crucial role, so I started with EM radiation and its spectrum. Next video, I discussed the nucleus and constituted particles. As we will use nuclear properties, so essential to know all about the nucleus, nuclear particles, nuclear spins, etc. As NMR is all about the nuclear spin. So need to have a knowledge of spin and how we assign the spin to nuclei. So for this, I made two videos related to the nuclear shell model from which we can predict the spin value of a nucleus. Due to different spin values, nuclei form different spin states in the presence of an external magnetic field for each nuclei having non-zero spin values. In NMR spectroscopy, the nucleus is precise in a different direction in the presence of external magnetic called Larmor precession. The precession frequency is called Larmor frequency, and Nuclei absorb the radiation of frequency equal to Larmor frequency. In a different chemical environment, each proton experiences a different magnetic field due to the induced magnetic by electrons. Thus, each type of proton absorbs a different frequency and gives a different NMR signal in NMR spectroscopy. NMR spectroscopy is quite helpful in counting different types of protons and the total number of protons present in a compound. The total number of protons can be found by integrating the NMR signal or calculating the area under the peak. #nmrspectroscopy #nmrspectrosocopyorganicchemistry #netspectroscopy
