Maximum wavenumber is 3000 cm-1

[minouHub]

Hello,

I'm using more and more this amazing app. However, I'm usually bothered by the limit at 3000 cm-1. Why such a limit?

Best,
Nicolas

It's very arbitrary, sorry about that! Do you know what would be a good lower and upper bounds?

[minouHub]

don't be sorry, this work is amazing and has a bright future in my opinion. Btw, is there a way to check the trend of use?

I think that there are no limits. For the H2O molecule, the minimum wavenumber is 0.000084 cm-1 and the maximum is 25710.825500 cm-1. I don't know if it makes sens to go so low in wavenumber. I would (arbitrary!) suggest:

• min : 1 cm-1
• max : 30,000 cm-1

@minouHub is it OK now?

[minouHub]

amazing!

Two problems I didn't think about:

1. it is now difficult to precisely aim with the cursor.
2. Also, it is now tempting to perform calculations on very large ranges, which ultimately crashes the code.

Is it possible to allow for a larger scale but let the cursor navigate on 0 - 5000 cm-1? What do you think?

Sorry for reopening this issue

All good! I'll make the adjustments to the scale.

We could potentially replace the range slider and just rely on the input boxes if that would be better with the larger range.

I don't really know what would the best for users. I want the best of the two:

• I want to be able to simulate up the highest waverange I desire
• I also want to use the range slider sometimes because it is very easy to use

Is there a way to allow up to very high, but have the slider range on 0-5000 cm-1? What do you think?

Update on the scale . @arunavabasu-03 @suzil is it possible to have some kind of "log-scale spring slider"; i.e. :

initial position of the cursors would be approximately centered :

if I move a bit to the right, it allows me to make precise changes :

If I go further to the right, i get exponentially larger changes , i.e. :

Hence the "Log-scale effect"

Now, when I release the cursor, the two sides of the cursors spring-back to the initial position (approximately centered), but with the new range. This allows me to iterate quickly, and be very precise, from the new position.

In terms of UX I think it's quite good @minouHub

hmmm funny now the cursor is on 2 lines for me

I really think the cursor is fine like this. I don't use it anyway because I usually know which bounds I want to simulate and directly type it
