The leading principles of the method are straightforward. To calculate a given electronic state, all the Lewis structures that are relevant for the qualitative VB description of this state are generated, and the covalent forms are distinguished from the ionic ones. Each of these Lewis structures is represented by a single VB function which has its specific set of orbitals. The orbitals and the coefficients of the VB structures are optimized simultaneously, to minimize the energy of the final multi-structure state. 

Laser Diffraction Methods Over the past 30 years laser diffraction has developed into a leading principle for particle-size analysis of all kinds of aerosols, suspensions, emulsions, and sprays in laboratory and process environments. 

Comparing models (5.1) and (5.2), it is also clear that model (5.2) has more parameters (six) to estimate than model (5.1), which has only three parameters to estimate. Given the same amount of data, the parameters in model (5.1) are estimated with more degrees of freedom. Hence, the variances of the estimated parameters in model (5.1) are lower than the variances of the analogous parameters in model (5.2). This points to a trade-off between fit and variance, and this is indeed one of the leading principles of model building. If model complexity is defined in terms of the number of parameters which have to be estimated, then model (5.2) is more complex than model (5.1). 

The concise symbolic notation of modern chemistry, although much less picturesque than alchemical symbolism, enables chemical changes to be represented very simply and fully, particularly by means of chemical equations. These equations embody the leading principle that the chemist must cultivate two-dimensional thou t he must learn to interpret chemical symbolimn both qualitatively and quantitatively. For example, the complete expression of Cavendishes explosion of a mixture of hydrogen and oxygen is given by the equation ...

Further problems are caused by the need for precision and accuracy. A method for determining accuracy would be to add a known quantity of the natural leading principle, but often this is simply not possible as the compound is not available in sufficient quantities.
