Podcasts on basic chemistry concepts???

[alfabeta]

Hi all,

I am hoping someone can help me out.

 

I am looking for some audio podcasts/audio books on the basics of Chemistry...

 

Like a audio "Introduction to Chemistry" text book.

 

I have found a lot of "introduction to Chemistry" lectures from Yale and Berkeley and on Itunes.

 

While I appreciate these, the problem with them is that they don't edit out the ramblings of the professors at the start. And mostly, the quality of the recording is poor and quite difficult to listen to on Public Transport.

 

I have done fairly extensive searching on and off over several months to no avail.

 

Is anyone aware of where i could find what I am looking for, either for free or for a fee?

 

Regards

Alf...
