Question

In microwave spectroscopy, the product of this quantity squared, the reduced mass, and the line spacing is always constant. At this quantity’s equilibrium value, the Morse potential is minimized. (20[1])The (20[1])strongest peaks (20[1])in an IR spectrum arise from modes that increase this quantity because it is directly proportional to dipole moment. (20[1])For a simple cubic crystal, this quantity equals the unit cell lattice constant and can be measured by (*) X-ray diffraction. (10[1])Resonance (10[1])explains why this measured quantity for ozone (10[1])is halfway between its value (10[1])for oxygen and oxide. (10[1])This quantity equals the sum of (10[1])two hard sphere radii and is roughly an angstrom (10[1])for two carbon atoms. For 10 points, name this distance between two (10[1])covalent (10[1])nuclei. (10[5])■END■ (10[12])

ANSWER: bond length [or bond distance; or bond radius; accept lattice constant until it is read; prompt on length or distance or radius]
