I am using the \NMR command of the chemmacros package. The format is bold. But as you see in the picture, the frequency "500 MHz" is not bold.

\documentclass{scrreprt}
\usepackage{chemmacros}
\chemsetup{modules=spectroscopy}
\begin{document}

\begin{experimental}[format=\bfseries,delta=(ppm),list=true,use-equal=true]
\NMR(500)[DMSO-\textit{d}6] \val{1.05} (s, \#{3}, \J(3;H,H){3}, \pos{4}), \val{3.05} (t, \#{3}, \J(4;H,H){7}, \pos{3})
\end{experimental}
\end{document}

enter image description here

How can I make the frequency also bold? I have tried it like this:

\documentclass{scrreprt}
\usepackage{chemmacros}
\chemsetup{modules=spectroscopy}
\begin{document}

\begin{experimental}[format=\bfseries,delta=(ppm),list=true,use-equal=true]
\NMR(\textbf{500})[DMSO-\textit{d}6] \val{1.05} (s, \#{3}, \J(3;H,H){3}, \pos{4}), \val{3.05} (t, \#{3}, \J(4;H,H){7}, \pos{3})
\end{experimental}
\end{document}

But this gives me an error. In the documentation of the package the frequency is also bold, when you write "format=\bfseries". So this could not help me. I am using "ShareLaTeX".

Thanks.

chemmacros use siunitx for typesetting values and units. (In particular, the section in the manual about the spectroscopy module starts with “The spectroscopy module loads the chemformula module and the siunitx package”.)

The siunitx package typesets everything as upright (usually non-bold) text. The last paragraph of the section “siunitx for the impatient” says:

By default, all text is typeset in the current upright math font.

The manual has comprehensive sections about this behaviour. In short: in your case you need to either use the detect-weight (for only detecting and adapting to the current font weight) or the detect-all option (for detecting and adaptiong to all current font properties):

\sisetup{detect-weight}

or

\sisetup{detect-all}
