Problem with \SIlist with two values and list-final-separator = {, }

Question

First and foremost, thanks to Joseph Wright for developing and maintaining siunitx package.

I have a problem with \SIlist macro. The desired result:

3.23 (dd, J = 3.9, 0.9 Hz, 1H).

and I'm using this code:

\num{3.23} (dd, \emph{J} = 3.9, \SI{0.9}{\Hz}, 1H).

It works fine but I thought I could use \SIlist macro and eventually automate things a bit:

\num{3.23} (dd, \emph{J} = \SIlist[list-units=single,list-final-separator = {, }]
{3.9;0.9}{\Hz}, 1H)

I get the following result:

3.23 (dd, J = 3.9 and 0.9 Hz, 1H)

A list of three or more values works OK:

\num{3.23} (ddd, \emph{J} = \SIlist[list-units=single,list-final-separator = {, }]
{3.9;0.9;0.1}{\Hz}, 1H)

3.23 (dd, J = 3.9, 0.9, 0.1 Hz, 1H)

Any ideas? Thank you.

Answer 1

You want list-pair-separator:

\documentclass{article}
\usepackage{siunitx}
\begin{document}

\SIlist[list-units=single,list-final-separator = {, }, list-pair-separator= {, }]
  {3.9;0.9}{\Hz}

\end{document}

I'd probably use \sisetup to do this globally.

Answer 2

Have had exactly the same question, funny. This is what I am using in my preamble to set most things right for chemists work with siunitx ;)

\sisetup{
    detect-family,
    alsoload        = synchem,
    list-units      = single,
    range-units     = single,
    range-phrase    = --,
    list-pair-separator= {, },
    list-separator  = {,},
    list-final-separator = {,},
    per-mode        = fraction,
    exponent-product = \cdot
    }
