College research personnel also have access to the instrumentation and services (NMR, MS and proteomics) of the Ohio State Campus Chemical Instrument Center, including the 600 and 800MHz NMR spectrometers located adjacent to the college’s 400MHz instrument. Simple pKa estimation. the entire NMR spectrum of the proposed model [10, 13].
