I'm a Jmol newbie. Could someone please explain this to me? Is it about
the stand-alone apllication or using the jmol.js applet?

In the use of jmol/js in web application, the right click menu has an
item for defing the units of measurements. However, I can not figure out
how to display bond legths and bond angles on the molecule image. Is
that possible? Is Chris' message above anything to do with this?

Brian.

It is about both the Jmol application and the JmolApplet

(Jmol.js is a JavaScript library that helps build web pages using the
JmolApplet)

 In the use of jmol/js in web application, the right click menu has an
 item for defing the units of measurements.

Correct, this is for the units.

 However, I can not figure out
 how to display bond legths and bond angles on the molecule image. Is

Double click, optionally single click 0, 1, or 2 times, Double click

After your first double-click the cursor will change and then you can
'hover' over several different atoms to get different distances.

Move outside the applet to cancel the measurement.


For a distance measurment:

double click to drop an anchor
double click on the destination

for an angle measurement:

double click to drop an anchor
single click on an intermediate point
double click on the final point

for a torsion measurement:

double click to drop anchor
single click
single click
double click
