We investigate the effectiveness of creating polar ground-state KRb molecules by two-color photoassociative spectroscopy. In this process the molecules are formed from ultra-cold samples of K and Rb. Focusing on spin-polarized atoms we show that an effective pathway exists. In addition, we investigate the stability of the polar molecules in the presence of a thermal black-body radiation field.
