General ⇒ New Command with Math Mode inside

[zaphod]

Hello everyone,

I'm currently writing my master thesis and decided to do this with TeXmaker. I'm a total newcomer to LaTeX and TeXmaker and still make a lot of mistakes. This is the critical line:

Code: Select all

\newcommand{\photons}{\mu $ mol photons/m^{2}s $}

Every time I use the new command \photons I get the following error message:

Code: Select all

! Missing $ inserted.
<inserted text>
$
l.111 ...mum working PFD close to $ 200 $ \photons
for biomass growth }
I've inserted a begin-math/end-math symbol since I think
you left one out. Proceed, with fingers crossed.

Can you help me?

Since \mu is a math mode symbol, it has to be put into math mode.

Code: Select all

\newcommand{\photons}{$\mu mol photons/m^{2}s$}

Untested due to missing minimal example.


Best regards and welcome to the board

Thanks for the fast reply!

Didn't know I should post a minimal example.
I'll do it the next time!

Thanks and by

So you probably have neither read “Avoidable Mistakes” nor the “Board Rules”?
