The vibrational frequencies of polyatomic molecules derive from (a) the masses of the linked atoms, (b) their geometric interrelationships, and (c) the forces due to deviation from equilibrium bond config

He also recognized the need for means to bridge the communication barriers inevitably genera ted by such an evolution, and this conviction largely stimulated us to write this book. Membrane technology is a vast field and we cannot treat all its aspect

As far as defined macromolecules are concerned, the data on RNA and DNA remain fragmentary, and membrane lipids are not macromolecules, but aggregate into supramolecular complexes in aqueous solvents; thus, membrane proteins constitute the major macromolecula

Absorption of electromagnetic radiation of appropriate frequency (range 1–220 MHz) can raise the potential energy of the nuclei, forcing realignment of their magnetic moments in the applied field. Nuclear magnetic resonance (NMR) utilizes this and closely related phenomena, essentially mea

Optical activity has been widely reviewed (1–5); we, therefore, present only a few basics here before turning to membranes, whose optical activity derives almost exclusiv
