Counter clockwise rotation. Left-hand element. 

FIGURE 6.2 The amide or peptide bond planes are joined by the tetrahedral bonds of the ff-carbon. The rotation parameters are p and Ip. The conformation shown corresponds to clockwise direction ( + 180°) is equivalent to a rotation of 180° in the counterclockwise direction (—180°). (truing G s)... 

Using the example of a transportation maintenance facility, Figure 7.7 shows that a counter-clockwise rotation of the traffic flow could achieve minimum crossing and give a graduation of decreasing traffic density in the counter-clockwise direction as vehicles are diverted off the main stream (Figure 7.8). 

A second radial (Y-axis) measurement point should be positioned at 90° to the primary in a plane that captures secondary shaft deflection. For the pump illustrated in Figure 44.21, the secondary (Y-axis) radial measurement point is located on top of the pump s bearing cap and oriented downward. Since the pump has a clockwise rotation, back-pressure in the discharge piping forces the shaft both downward and horizontally toward the front of the picture. 

The location of the primary (X-axis) radial measurement point for this type of pump is in the horizontal plane and on the opposite side from the discharge. The secondary (Y-axis) radial measurement point should be 90° to the primary point and in the direction of rotation. If the illustrated pump has a clockwise rotation, the measurement point should be on top, oriented downward. For a counter-clockwise rotation, it should be on bottom, oriented upward. 

C4 11 t) -6, clockwise rotation about the z axis through 90° followed by the translation t, followed by time reversal ... 

Southward migration of Southwest Japan as a drawer between a right-lateral system to the west and a left-lateral one to the east along the Tanakura Tectonic Line (Otsuki and Ehiro, 1978) or a clockwise rotation of Southwest Japan about a pole located in the Tsushima Strait (Otofuji et al., 1987), or a combination of both (Kobayashi, 1983) have been proposed. 

If a proper rotation is combined with a reflection with respect to the axis of rotation, it is called an improper rotation The matrix representation of silvan operation is found simply by replacing 1 by -1 in Eq. (104), The Scftfllfllies symbol for an improper rotation by y is S /tp- Hence, matrix the representation of an improper counter-clockwise rotation by y is of the form ... 

The subscripts on the hydrogen atoms are to identify their positions. Clockwise rotation by 120° around the C3 axis results in the molecule having the orientation... 

We shall conventionally define as positive the clockwise rotations from the double bond nearer to the observer to the one farther away. 

This operation corresponds to a counterclockwise rotation of the vector r. Since cosf = cos(—9) and sin0 = — sin(—9), the matrix for clockwise rotation is... 

The matrix equation for clockwise rotation through 9 about the 2 axis becomes... 

That is, the effect of b2 can be reproduced by first performing the inverse of c, namely a clockwise rotation through 27r/3, then a n rotation about OY (considered as fixed in space) and finally undoing the first rotation3. There is another relationship between b2 and by, i.e. 

Next consider the effect of the symmetry operators on the clockwise rotations, defining RCUJ = 1, Racw = — 1. 

In contrast, with penicillins, cephalosporins, and monobactams where the substituents are cis to each other across the C3 - C4 bond, clockwise rotation can occur without conflict with protein side chains, and will leave the path open for the water molecule to attack and hydrolyze the ester group in B (Scheme 10). Thus, czs-substituted monobactam, as well as penicillins and cephalosporins are rapidly hydrolyzed by class C enzymes (Scheme 10). If this rotation could be prevented by a suitable structural modification, the access of the water molecule to the ester bond will be blocked, which would result in increased stability of the acyl-enzyme complex. 

From the diameter of the disclinations, the pitch can be measured30 furthermore, clockwise rotation of the lens generates a shrinking or an expansion of the circles, according to the cholesteric handedness from this, the helical handedness can be deduced.31 It should be stressed that this is not a spectroscopic method and gives results completely independent from those obtained with CD or optical rotation. 

The numbers 2, 3, 4 and 6 are used as symbols of the corresponding axes of symmetry while the symbols 3, 4 and 6 (3 bar, 4 bar, etc.) are used for the three-four- and six-fold (roto) inversion axes, corresponding to a counter-clockwise rotation of 360% around an axis followed by an inversion through a point on the axis.
