• technique for determining changes in chemical interactions and molecular geometry in LC phases [37][38][39][40], we investigated the 73 mol % BB mixture using temperature-dependent FTIR measurements. IR spectra were recorded using a KBr pastille method. Since in a binary mixture the cyano group of CBI may

According to the phase diagram, the induced smectic phase is most stable in the mixture containing roughly 70 mol % of BB
