Rotframe.m
Rotating frame transformation with respect to a specified group of spins to specified order in perturbation theory. Syntax:
H=rotframe(spin_system,C,H,isotope,order)
Parameters:
C - carrier Hamiltonian with respect to which the rotating frame transformation is to be done
H - laboratory frame Hamiltonian H0+H1 that is to be transformed into the rotating frame
isotope - string, such as '1H', specifying the spins with respect to which the transformation is being computed
order - perturbation theory order in the rotating frame transformation
