Opis

Various major and minor digital equipment used for experimental work are discussed. The block diagram and the principle of the application are also detailed. The accuracy of the measurement with respect to the input signal are explained. Each of the instruments is calibrated with a standard before introducing the sample under investigation. The digital output data elucidated from all the instruments is stored in desired memory location and retrieved to draw the graph using respective soft wares. Design and synthesis of three homologous series and eleven binary complexes comprising of 121 mesogens is discussed elaborately in the above sections. Phase variance exhibited by the individual complexes with the corresponding mesogenic thermal range along with molecular formula and molecular weight are tabulated in separate tables. Smectic X is a new phase which is observed in the above investigations. Chemical spectroscopy namely FTIR and NMR spectra of various mesogens has been discussed in the above sections in detail. The precursors spectroscopic details are also discussed and compared with the corresponding complexes.
