How to get coupling constants from this spectra. Values at the top are in ppm. The instrument is 300 MHz.
Make a sketch, roughly to scale, of the 1H NMR spectrum expected for an AX spin system with δA = 1.00, δX = 2.00, and JAX = 10 Hz recorded on a spectrometer operating at (i) 250 MHz, (ii) 800 MHz. The horizontal scale should be in hertz, taking the resonance from TMS as the origin.

How do I solve for [FeSCN2+] heres the formula they provided me and my data but I would like steps on how to solve it and what data I should be using to solve for it u can use any fake numbers you need to help me understand ! I'm confused only by the absorbance part , what number am I using for the absorbance? Is it Fe3+ added to ScN- absorbance values ? also e = 202 and L = 1.0
A proton has resonance at 90Hz downfield from TMS when the field strength is 1.41 T(14,100 Gauss) and the oscillator frequency is 60MHz. What will be the shift in Hz if the field strength is increased to 2.82 T and the oscillator frequency to 120MHz? what will be the chemical shift in parts per million ?
