Awwad %A T. Sahlabji %J - %D 2018 %X This article summarizes the protonation and complexation equilibrium constants of nicotinic acid (NA) using different analytical techniques and software¡¯s. Additionally, Raman, IR, and NMR spectra were done for nicotinic acid ligand and for its solid complexes with copper(II), cobalt(II) and nickel(II) metal ions. %U https://www.ajol.info/index.php/bcse/article/view/180046
