The formula of [Mn(phen)3](CF3SO_3)_2.6, 5H20 was then proposed. The corresponding IR spectrum indicated the presence of typical function group of phenantroline and the triflate ion in the complex. The complex was found to be yellowish, and paramagnetic(μ_(eff)=5.8-5.95 BM)...

The chemical shift perturbation (CSP) upon CDZ bind- ing to holo-CaM was determined from the differences of 15N (∆δN) and 1HN (∆δHN) chemical shifts of the free and bound forms using the formula: CSP = (0.159 × �δN )2 + �δ2HN The translation (d) and rotational ...

The NMR chemical shifts for the aromatic protons and carbons were found to be within the expected range. The inte- gration values were completely consistent with the chemical formula of the compounds. The 1H NMR spectrum of C1 did not show any resonance signal for O-H proton. However, the ...
