The pka of DBU in acetonitrile is 24.34. The pKa values are affected by temperature and the solvent dielectric constant. Is there a formula to convert pka values from one solvent to another as well as temperature?
There are propiertary software where you can simulate it, but empirical methods have still no rival
Recently I was suggested to do Parallel Analysis and compare with EV>1 to determine no of factors for my scale. However, the scale I have developed uses Principal Axis Factoring and not PCA. If...
