Molecular quantum mechanical observers, symmetry, and string theory

The paper \cite{Dance0601} tentatively suggested a physical picture that might underlie string theories. The string parameters $\tau$ and $\sigma_i$ were interpreted as spacetime dimensions which a simple quantum mechanical observer can observe, while symmetries of the relevant observer states could limit the observability of other dimensions. An atomic observer was the focus of the discussion. The present paper extends the discussion of\cite{Dance0601} to molecular observers, including the nature of some common molecular bonds and their symmetries.
