Motion patterns of the normal modes of deformation of Lf. a) Mode 6 is a torsion motion, which is suppressed by a steric hindrance (relevant section magnified). b) Mode 7 of open-open resp. mode 8 of closed-closed structure. c) Mode 8 of open-open resp. mode 7 of closed-closed structure. d) Mode 9 and e) mode 10 are the same for both structures
