Every thing that falls in to the category telephones, radio, television
and microwave.
My question is more complicated. Is it possible to get some compound or
chemicals. Alter their structure so that the chemical or compound will
be only affective when someone sends a RF wave. I don't know if I can
say it this way ..but polarize, make it only react with the water when
the specific RF is send.
Lets say a chemical that normally when put in a sea water turns the
water red. Now is it possible to somehow alter the chemical that when
put in the water will not turn the water red but only when you transmit
a radio frequency wave will turn the water red?

Hello
I don't know what is the best way to ask this, so I'm going to say it
in my plane language.
Is it possible to change the structure of chemicals with radio
frequency..?

Radio frequency what? Electrical voltages, rf-band em radiation,
rf-modulated visible light, rf-modulated electric fields, rf-induced
plasmas?

And yes, that is a serious question, not a sarcastic response - you
need to be more specific. Here's some examples:

Chemists use microwave ovens to speed up chemical reactions.

Microwave-induced plasmas are used to completely dissociate molecules
into atoms and monatomic ions.

Low-intensity rf-band em radiation is used to study molecular structure
without destroying or altering the molecule(s) in question.

I'm sure others can add additional examples...

Some people just can't stand it and will never admit to the truth about
s**t-madzu even if it is shoved in front of their slanted foreheads!

Look at the above picture.
Using my model for the atom, I can do the same thing with
every atom and molecule.
This could be built in the real world quite easily.

Why?

What does this have to do with analytical chemistry?

Come to think of it, what does it have to do with chemistry?

I'm working on an orbital system that centers
on the points of a cube for explaining elecron
orbitals. See
http://users.accesscomm.ca/john/cubepath.GIF
and
http://users.accesscomm.ca/john/cubepath1.GIF
On March 7 I found how two of
these join to form a molecular orbital, which is
a. 25% shorter
b. dictates that both members go on both sides
of both paths. See
