Here is how you calculate a coupling constant J: For the simple case of a doublet, the coupling constant is the difference between two peaks. The trick is that J is measured in Hz, not ppm.
The first thing to do is convert the peaks from ppm into Hz. Suppose we have one peak at 4.260 ppm and another at 4.247 ppm. To get Hz, just multiply these values by the field strength in mHz. If we used a 500 mHz NMR machine, our peaks are at 2130 Hz and 2123.5 respectively. The J value is just the difference. In this case it is 2130 - 2123.5 = 6.5 Hz This can get more difficult if a proton is split by more than one other proton, especially if the protons are not identical.
General gas constant is R = 8.31 J · K-1 · mol-1Air gas constant is Rair=R/28.97=0.2869 (J/g K)=286.9 (J/kg K)
It depends on the element that you are using, and what state the electron is in. In general this is a dimensionless constant that is derived out of the quantum j, i, and f numbers that governs Zeeman Splitting

Resolution is affected by the strength of the B0 magnetic field. The j coupling (distance between lines in a quartet for instance) is a constant value in Hz. However the place that the lines appear is not. Increasing the magnet increases the distance between features while keeping the j coupling from overlapping (thus allowing independent, resolved peaks
The universal gas constant is denoted by R = 8.314 J/kgK, (but not G which denotes the Gibbs free energy of a given reaction at given conditions.
To calculate the energy of emitted light, you can use the equation E = hν, where E is energy, h is Planck's constant (6.626 x 10^-34 Js), and ν is the frequency of light. The value of the constant, Planck's constant, is 6.626 x 10^-34 Joulesseconds.
In NMR spectroscopy, a coupling constant is a measure of the interaction between different nuclear spins in a molecule. It provides information about the connectivity and relative arrangement of atoms in a molecule. The value of the coupling constant is influenced by the number of bonds and the dihedral angle between the coupled nuclei.
To calculate the J value for a triplet, use the formula J = 4 * Δν, where Δν is the distance in Hz between the outer lines of the triplet. For a multiplet (e.g., quartet), calculate the J value using the formula J = Δν / (n-1), where n is the number of peaks in the multiplet.

In SI units, the gas constant has a value of approximately 8.314 J / (mol x kelvin).
The constant for 1 mole of any ideal gas is known as the ideal gas constant, typically denoted as R. Its value is approximately 8.314 J/mol∙K.
"Characteristic Gas Constant"The constant 'R' used in the characteristic gas equation PV=RT , has a constant value for a particular gas and is called 'Characteristic gas constant' or 'specific gas constant' . Its value depend upon the temperature scale used and the properties of the gas, under consideration.The value of R will be.For atmospheric pressure air,R= 287 J/kg/k
