The surface of erythrocyte contain a number of antigen or agglutinogens on their surface which are composed of glycolipids and glycoproteins. Based on the presence and absence of various antigens, blood is characterized in different blood groups. Within a blood […]
• COMCEPTS OF ELECTRONIC STATES 1. Ground state :- It is state of electron in which lowest energy states and highest stable. 2. Excited state :- It is state of electron in which highest energy states and lowest stable. 3. […]
Factor that affecting fluorescence :- 1. Nature of the molecule :- Molecules that have tendency to absorbed Electromagnetic radiation (uv,IR) can only exhibit fluroscence. Unsaturated molecules with pi(π) bond and good resonance that molecules exhibit fluroscence. Saturated molecules with sigma(σ) bond do […]
INSTRUMENTATION OF Fluorimetry 1. Source of light: In Fluorimetry there are mainly three types of lamps are used A. Mercury vapour lamp :- At high pressure Mercury lamp give 350 nm to 734 nm region radiation. At low pressure Mercury […]
NUMERICAL PROBLEM OF NMR Q-1. Proton that have resonance at 110 Hz Downfield from TMS on nmr spectrophotometers it’s operates at 50Hz so, calculated the chemical shift ? Q.2 If the observed shift from TMS is 500Hz and operated frequency […]
NMR NUMBERCAL QUESTIONS Q.1 if 2000 microgram paracetamol is dissolve in 0.1N NaoH. So what is concentration of solutions ? Ans. We know that, 1000 microgram=1gram 2000 microgram = 2 gram If we disolved 1 gram in 1 litre this […]
¹³C NMR Although ¹²C is not observed in NMR,only ¹³C is observed in NMR. ¹³C is 1.1% present in nature. The relatively low abundance of ¹³C is over come by using single avaraging and Fourier transforms. ¹³C (267.53) has lower gyromateric ratio as compared […]
