In this study, the IH-IH, lH31P and13C-3lP coupling constants of the branched RNA tetramer 2 have been measured at two temperatures to obtain detailed information about its backbone conformation. Evaluation of these coupling constants by Karplus-Altona algorithm shows the decrease of populations of
