A Understanding the Limitations of Electron Spin Resonance
Hello, I have a question regarding the limitations of Electron Spin Resonance (ESR). I've read somewhere that ESR cannot detect radicals with short lifetimes. I'm trying to understand why is that? For example: a highly dynamic system like liquid sulfur at high temperatures, where sulfur...- sha1000

Choosing a pulse capacitor, ESR vs reactance at frequency
While going through the catalogues I started to wonder, typically lower ESR caps cost more, but if I need the cap for DC smoothing , to filter out unwanted AC ripple, then I put that cap across my DC rails +-. Now so far so good. It's ability to filter out the AC ripple will be directly related...- artis

Microwave transparent material for ESR/EPR spectrometer
Hi! Completely forgot about this great forum! I'm designing an electron spin resonance /electron paramagnetic resonance spectrometer, as an easier vacation from my diy NMR - while still utilizing much of the same setup. Issue is; I have an X-band (~12GHz) waveguide cavity in a magnet, and I...- C.Braestrup

Capacitors in parallel for lower ESR question
so I am facing the need for low esr and high ripple current for a smps output filter after rectifier. Would it be better in terms of both ESR and ripple to put say 8x470uF in parallel or 4x1000uF ? Or maybe there wouldn't be a big difference ? Assuming both caps are with a low esr and high...- Salvador

What does the g-factor, from say ESR, tell you?
From ESR data you can extract the g-factor and "effective" magnetic field. Let's say I get this g-factor from ESR, what does it tell me? i.e. "if the g-factor is X then Y is happening in the system". What specific information can I get from knowing this factor? What causes it to differ from...- maverick_starstrider

ESR Spectroscopy: Hydrogen vs. Deuterium G-factor
Hi. I did an esr-experiment, analyzing hydrogen and deuterium. I am wondering: Why do the atoms not have the same g-factor?- Kulkid

Paralleling capacitors effect on total esr reduction.
Hi and thanks for taking the time to read this post. I am trying to decide component values for 2 parallel capacitors, in an effort to reduce esr, which will be for use as power supply smoothing capacitors to be placed after the bridge rectifier. After examination i noticed that consumer...- goodguy

Switching losses ESR and transient response
I need someone to tell me if what I am saying is true or BS? Switching Frequency: Is simply defined as the frequency (amount of times) the same operation occurs, in our case the amount of times per second each phase is switched on. Duty Cycle: is thought of as the time the object is on...- ssb2245

Drastically decreasing capacitor ESR
Hey all, I'm and Aerospace undergrad at Cal Poly working on my senior project, which has turned out to be more of a EE project than anything else. Anyways, I'm building a capacitor bank for the firing of an electromagnetic rail gun. I'm attempting to make a PFN (pulse forming network)...- jmaniglia
