A torsional quartz crystal method was used to obtain the complex shear mechanical impedance of cholesteryl nonanoate at 150 kHz. The apparent shear modulus evaluated from the measured impedance shows a finite value of 〜10^4 cgs in the middle of the cholesteric phase. The observed shear elastic behaviour can be interpreted in terms of the existence of an apparent layer compression modulus in the cholesteric phase, which gives rise to the second sound mode similar to that in the smectic A phase.
