AB Spin System: Simulation

Contents

This page contains:

1. a form to simulate an AB NMR spectrum.

For general information on the AB spin system, see this page: AB, General Information.

Input Section

Please enter the spin-spin coupling constant JAB (in Hz), the chemical shifts of nuclei A and B (in ppm), the frequency SF of the reference compound (in MHz), as well as the desired total width of the simluated spectrum in pixels (be reasonable ;-):

JAB:	Hz
dA:	ppm
dB:	ppm
SF:	MHz
width:	pixel

 

Solution

fo:	500.00 Hz
D:	40.00 Hz
JAB:	10.00 Hz
D/JAB:	4.00
2C:	41.23 Hz
(2C-D)/2:	0.62 Hz / 0.01 ppm
vA:	520.00 Hz	dA:	5.2000 ppm
vB:	480.00 Hz	dB:	4.8000 ppm

v1 =	525.62 Hz	I1 =	0.7575	plot limits:
v2 =	515.62 Hz	I2 =	1.2425	high frequency:	530.74
v3 =	484.38 Hz	I3 =	1.2425	low frequency:	469.26
v4 =	474.38 Hz	I4 =	0.7575
