Even though comparison is often difficult, it would be rendered considerably easier if the units used conformed to the SI system of weights and measures. Thus, the meter, newton, and pascal should be used as the units of length, force, and pressure, respectively.

At this stage, it is appropriate to draw attention to additional misuses of the concept of orbital hybridization, besides the relation with molecular geometry already discussed. We will briefly refer here to frequent interpretations of differences in bond energies, bond lengths, force constants, bond polarity, acidic character, etc. (see ref. 117). 

In this molecule, which has a very small (possibly zero) dipole moment, the bond length is M31 A. The length, force constant, and bond energy (Table 21.4) show that it is best represented C=0.

FIGURE 7 Release (a,) and restretch afterS ms (aj) in a contracted skinned taenia coli fiber. The fiber was stretched above the initial length and released 2 ms later (aj). A stretch (b,) from the initial length and return release (bj) are also shown. Panels as in Fig. 6. Dashed lines in lower panel indicate slope of length-force relation (stiffness) in initial release (aj) or stretch (b,), and in restretch after unloaded shortening (aj). Note lower slope (=stiffness) after shortening. From Arheden and Hellstrand (1991).

As discussed in the text, the slug and the poundal Were invented to make the conversion factor (mass length)/(force time ) have i coefficient of 1. A new unit of length or a new unit of time could just as logically have been invented for this. Let us name those units the toof and the dnoces. What are the values of the toof and the dnoces in terms of the foot and the sjecond j... 

We may choose as our dimensions length, force, and time, in which case we must express the density in dimensions of force times (time) divided by (length) and the viscosity in force times time divided by (length). In this case + 1 equals 6, and k equals 3. Can we find three parameters which cannot be combined into any dimensionless group Yes, the force, one of the lengths, and the density cannot be so combinejd the three dimensions are independent, and the number of -tt s is 6-3 =j3. 

In this choice of dimensions the independent dimensions are length, force, and time. We now construct a table of the variables, indicating their dimensions.

Once we have identified the system, its boundaries, and its interactions with the surroundings, we must describe the condition of the system. This description involves certain quantities, called properties, whose values depend only on the current condition. We take properties to be macroscopic concepts microscopically, there are additional quantities, such as bond lengths, force constants, and multipole moments, that describe molecular structure and define intermolecular forces. These microscopic quantities are not properties, but they contribute to the values taken by properties.

Raman spectroscopy of conducting polymers has mainly treated the structures of intact polymers (geometry of polymer chains, conjugation length, force field, etc.) [13-15]. Although the Raman spectra of doped polymers have been reported [13-15], the observed Raman bands have not been correlated to the types of self-...
