I got a big text file with data from a spectroscopy.

The first few lines are like these:

```
397.451 -48.38

397.585 -48.38

397.719 -48.38

397.853 -18.38

397.987 -3.38

398.121 6.62

398.256 -0.38

398.39  -1.38

398.524 7.62

398.658 4.62

398.792 -4.38

398.926 12.62

399.06  5.62

399.194 -6.38

399.328 -6.38

399.463 0.6

399.597 -6.38

399.731 -12.38

399.865 1.62

399.999 2.62

```

What I would like to do is to create two lists where one contains e.g [397.451, 397.585, 397.719.... etc]

And the other [-48.38, -48.38,-48.38, -18.38,-3.38 ...etc]
