For example, in I3, the χ2 angle has decreasing preference for rotamers in tr \u003e g+\u003e g− when χ1 is in the g+ state, but has a preference for rotamers in g− ≫ g+,tr when χ1 is g−. In I61, the χ2 has decreasing preference for rotamers in tr \u003e g− \u003e g+ when χ1 is in the g− state, but has a preference for g+\u003eg− \u003e tr when χ1 is g+. As appreciated from Fig. 7, these combinations of χ angles indicate that I3 adopts a more narrow and elongated conformation whereas I61 is wider and shorter. Similar correlations between χ angles can be made for I36 and I44.","tracks":[]}
