I got stuck with the following:
According to Markus Kohm (Koma-script) one can declare a new command for
sub-scribing chemical formula such as
H_2
by declaring a new command \Molek
\newcommand*{\Molek}[2]{#1\texstsubscript{#2}}
which I did by putting this in the preamble of my Koma-book document.
In the text I write in an ERT-box
\Molek H{2}
but get 'Undefined control sequence' \Molek H{2}
Same error, if I put only
\Molek
in ERT
and
H{2}
afterward.
I use koma(book) for my LyX document.
Can somebody give me some help?

Replace the mis-spelled "\texstsubscript" with "\textsubscript". (No 's'
in "text")
You also need:
\usepackage{fixltx2e}
in the preamble, so that the \textsubscript command gets defined.
Note that this way of using \Molek only works with single-letter atoms.
For chlorine, you need something like \Molek{Cl}{2}
You may want to have a look at the chemsym and bpchem packages,
that lets you typeset all sorts of chemical formulae.
