In principle, there exists an independent way of determining ojq. So and rj. The theory predicts the existence of sidebands at 1 Ixoq. The strength of these combination bands should be (dcu/ct>o) /8 of the fundamental mode with a width equal to We investigated very carefully the c(4 x 2) CO/Ni(lll) system without being able to detect these bands. It is not clear whether this is because the bands are too weak (1 x 10 )and/ortoobroad(40cm )orthat it has a more fundamental reason. [Pg.20]

Chemistry is the science that studies the nature and interconversions of material systems. Observed chemical patterns should therefore be reducible to the structure and properties of space-time and the assumptions of cosmology. However, unlike the theory of relativity, the fundamental periodic laws of chemistry find no detectable basis in standard cosmology. [Pg.16]

The theory of sonic-electronic level measurement is fundamentally based on a sound wave emission source from a transmitter, and a reflection of the sonic wave pulse to a receiver. Measurement of the transit time of this sound pulse and its correlation with electrical impulses provide a means for liquid level detection. Two basic designs operating on this principle use the vapor phase and the liquid phase methods. As most of the attention is currently devoted to the latter type system, this discussion deals exclusively with ultrasonic gaging over a liquid path. [Pg.403]
