Infrared properties of $\theta$-type ET charge-transfer salts: $\theta$-ET${}_2$CsZn(SCN)${}_4$ vs $\theta$-ET${}_2$RbZn(SCN)${}_4$

We performed polarized far-infrared reflectance measurements at different temperatures on $\theta$-ET${}_2$RbZn(SCN)${}_4$ and $\theta$-ET${}_2$CsZn(SCN)${}_4$, two typical charge-transfer salts in…
