H1NMR values are chemical shifts observed in nuclear magnetic resonance spectroscopy. NMR is a technique used to study the structure and properties of molecules.

• H1NMR values refer to the chemical shifts observed in proton nuclear magnetic resonance spectroscopy.

• NMR is a powerful analytical technique used to study the structure, dynamics, and properties of molecules.

• It involves the interaction of atomic nuclei with a st...read more

I have handled various instruments in my research work.

• Microscopes for observing samples at high magnification

• Spectrophotometers for measuring the absorbance or emission of light by substances

• Centrifuges for separating components of a mixture based on density

• PCR machines for amplifying DNA sequences

• Electrophoresis equipment for separating DNA, RNA, or proteins based on size and charge

HPLC stands for High Performance Liquid Chromatography. It is a technique used to separate, identify, and quantify components in a mixture.

• HPLC works on the principle of differential partitioning of analytes between a stationary phase and a mobile phase.

• The stationary phase is a solid or liquid material packed into a column, while the mobile phase is a liquid solvent that carries the sample through the column.

• Analytes ...read more

Chloro and bromo pattern ratio refers to the ratio of the number of chloro and bromo substituents on a molecule.

• The chloro and bromo pattern ratio is calculated by dividing the number of chloro substituents by the number of bromo substituents.

• For example, if a molecule has 2 chloro substituents and 1 bromo substituent, the chloro and bromo pattern ratio would be 2:1.

• The chloro and bromo pattern ratio can be used to det...read more
