I Bond length

Fig. 4-2. Optimized STO-3G structure for the benzenediazonium ion. I Bond lengths (pm) and angles. Non-independent angles are shown in parentheses.

The illustration shows a typical result. The absorption reaches a maximum whenever the Na-I bond length returns to the length to which the second pulse is tuned. The peaks show that the sodium atom moves away from the iodine atom (corresponding to the dips in the curve), only to be recaptured...

P212121 Z = 4 D = 2.01 R = 0.04 for 1,611 intensities. The compound is a minor product in the synthesis of methyl tyveloside. The pyranose conformation is a distorted 4, with Q = 66 pm 6= 162° (p=H8a. The (methylthio)carbonyl side-chain is extended. The C-S bond-lengths are 174.8, 179.1 pm. The C-I bond-length is 215.2 pm. The absolute configuration was confirmed by using the anomalous-scattering factors of the iodine atoms.

During studies on the interaction between sulfur donors and suitable acceptors, the solid-state structure of the charge-transfer adduct l,3-dithiane-2-thione- -diiodine 111 was investigated <1999IC4626> the CS3 moiety is planar, the I2 molecule lies in the same plane with the first iodine atom separated by 2.755 A and the I-I vector is practically co-linear with the S-I one. The I-I bond length is slightly elongated with respect to a free iodine molecule. 

Figure 12. Theoretically obtained plots of In (Q(f) 2(0)) versus t (where t is scaled by t 2, isc = [mcH cHii/kBT]1 2 1.1 ps ) for the first three quantum levels (n = 1,2,3) of the CH3-I mode in CH3I from the friction estimates (shown in Figs. 10 and 11) and the vibration-rotation contribution. The equilibrium CH3-I bond length was set to re = 2.14 A. The results show an increasing Gaussian behavior in the short-time scale with increasing quantum number n. This figure has been taken from Ref. 133.

The cis Sn—I bond lengths in the ketone 5641242 and ester 338b347 are 2.835-2.857 and 2.777-2.780 A, respectively, longer, as expected, than the tin-iodide bond lengths in tetrahedral four-coordinate diorganotin diiodides (2.67-2.72 A)172,1247,1248.
