Woodward fieser rule :- In 1945 Robert Burns wood ward gave certain rule for correlating λmax with molecular structure. In 1959 Louis Frederick Fieser modified these rules with more experimental data and the modified rule is known as wood ward fischer […]
Chromophore It is a covalently unsaturated group which is responsible for absorption of UV or visible radiation and may or may not impact in colour to the compound. A compound which contains chromophore it is called chromogen. In unsaturated linkage […]
ADVANTAGE Sensitivity :- it is give accurate result even sample is present in microgram concentration in solution. Precision :- upto 1 % can be achieved easily. Specificity :- This method is more specific than absorption method. Range of Application :- […]
Basic terms of NMR SPECTROSCOPY 1. Proton :- IT is a positive charge particle that present in nuclei of any molecule. 2. NMR SPECTROSCOPY :- when EMR are applied in any sample in presence of magnetic field. So that sample […]
INSTRUMENTATION OF UV-VISIBLE SPECTROSCOPY :- Radiation source Monochromator COLLIMATING SYSTEM Filter Sample cell Detector Sample cell :- Sample cell are used to hold a sample solution. The material of sample cell should not absorb at the wavelength being observed. Sample […]
LUNGS These are the two cone shaped organs present in the thoracic cavity which are separated by other structures present in the mediastinum. Even if one lung collapses due to some trauma the other lung remain expanded. The lungs are […]
