Nuclear  magnetic resonance involved the interaction between an oscillating magnetic field of electromagnetic radiation and the magnetic energy of the hydrogen nucleus or some other types of nuclei when these are placed in an external static magnetic field. The sample absorbs electromagnetic radiations is radiowave region at different frequencies since absorption depends upon the type of protons or certain nuclei contained in the sample.All nuclei carry a charge, so they will possess spin angular momentum. The moment of the spin angular momentum is quantized i.e. only those nuclei which have a finite value of spin quantum number(I˃0) will precess along the axis of rotation. From the exam point of view like CSIR-UGC-NET in Chemistry and GATE in Chemistry, NMR  spectroscopy is very important branch of chemistry. Therefore  many questions are asked from NMR spectroscopy  in CSIR-UGC-NET in Chemistry and GATE in Chemistry. The questions of NMR are key topic for all th...

An organometallic compound is defined as one that contains atleast one direct metal-carbon bond. This excludes some carbon compounds which are considered to be inorganic such as carbides (like calcium carbide) and cyanides (like sodium cyanide). The carbon containing groups may be carbonyls, alkyl, alkene, aromatic, cyclic or heterocyclic. From the exam point of view like CSIR-UGC-NET in Chemistry and GATE in Chemistry , organometallic chemistry is very important branch of chemistry. Every time, so many questions are asked in CSIR-UGC-NET in Chemistry and GATE in Chemistry. It is the key topic for all the institute preparing for CSIR-UGC-NET in Chemistry, GATE coaching in Chemistry . Day by day, the competitive level of any entrance examination of different academic programmes from the renowed Institutions and Universities are very chalenging. This is mainly because; every day more students are involving in competition to shape their career with the help of these programmes rel...

With the high increasing rate of competition with each passing day, it is difficult for the students to cope up with the fear and pressure. But to make the competition simpler and easier all you need is a good guidance and best institute. One really should know about all the possible prospects in chemistry and chemical sciences. Certain topics that hold a major portion of the paper of IIT-JAM, NET, GATE include topics like solid state, organomettalic chemistry, coordination chemistry, stereochemistry and many more. Catching hold over these topics will lead to definite success path in these competitive exams like CSIR-NET, GATE, IIT-JAM. In case of CSIR-NET (or CSIR-UGC-NET/JRF),  the eligible candidates may apply Online through a link available at CSIR, HRDG website: www.csirhrdg.res.in . In order to apply Online the candidates are required to download Bank challan Performa from the above website and then deposit the requisite examination fee in any of the Indian Bank br...

Laws of crystallography Crystallography is the branch of science which deals with the geometry, properties and structure   of crystals and crystalline substances. It is based on three fundamental laws. The law of constancy of interfacial angles : It states that the size of the faces or even shapes of the crystals of a substance may vary widely with conditions of crystallization yet the interfacial angles between any two corresponding be 90˚ , irrespective of the size and shapes of faces. The measurement of crystal angles is important in the study of crystals. * Interfacial Angles- The crystals are bound by plane faces. The angle between any two faces is called an interfacial angle. It is indicated from the above figure that the shapes of crystals are different but the angle between any two corresponding faces is 90˚. 2. Law of rational indices (Hauy’s law): This law states that “the ratio between the intercepts on the axes for the different faces ...
