How to draw isotope like D

Hi,

How to draw isotope like BrCD3 in instant jchem? I did not find the option to do this.

Thanks.

Hi, 

If I clearly understand, there is an options in Marvin skatch: 

just draw for example D by keyboard than select "D" by click (it is going to be green) than go to menu "Atom>Isotope" and here choose the isotop from options.

See attached screenshot.

 

Hope it help

Best Regards,
