Alkyl C-H 置信度 1.0
“The bands at 956.69 is C-H bending cm-1 cm-1 (out of plane), at 1465.9 is C-H in plane bending (scissoring), at 2885 is C-H stretching cm-1”

Borate 置信度 1.0
“cm-1 As suggested by reported literature, peak at 956.69 is caused by the presence of B-O stretching vibration of borate ion [70, 72, 74-76].”

Alkyl C-H 置信度 1.0
“Besides this, the band at cm-1 957 (2) and 964 (1, 3) disappears, which belongs to deformation in pyrrole rings being mixed with the out-of-plane CH-vibrations in benzene rings (Figures 4, 5).”
