Additional NMR Experimental Information
1 This structure was determined using standard 2D homonuclear techniques. 3JHNHA WERE OBTAINED BY FITTING LORENTZIAN LINES TO THE ANTIPHASE DOUBLETS OF HN-HA PEAKS IN A 2QF-COSY SPECTRUM PROCESSED TO HIGH DIGITAL RESOLUTION IN F2. 3JHAHB WERE EXTRACTED FROM A COSY-35 SPECTRUM ACQUIRED IN D2O
