Attribute: minShift
minimum value of shift allowed for AtomSite, in ppm. Is not set in normal cases. Together with maxShift serves to distinguish frequency-selective sites. The most common use is for distinguishing CO, aliphatic carbon, and 'just' carbon.
Aliphatic carbon: <90ppm
Aromatic carbon: 90-150ppm
CO carbon: > 150ppm
CA (for proteins): 40-90ppm
